Crimzon® ZLR16300  
Product Specification

Architectural Overview  
Maxim’s Crimzon® ZLR16300 MCU is a ROM-based member of the Crimzon ZLR16300  
family of general-purpose microcontrollers. With 1 KB to 16 KB of Program Memory and  
237 B of general-purpose RAM, Maxim’s CMOS microcontrollers offer fast-executing,  
efficient use of memory, sophisticated interrupts, input/output (I/O) bit manipulation  
capabilities, automated pulse generation/reception, and internal key-scan pull-up  
transistors.  
The Crimzon ZLR16300 architecture (see Figure 1 on page 3 and Figure 2 on page 4) is  
based on Maxim’s 8-bit microcontroller core with an Expanded Register File allowing  
access to register-mapped peripherals, I/O circuits, and powerful counter/timer circuitry.  
The Z8® core offers a flexible I/O scheme, an efficient register and address space  
structure, and a number of ancillary features that are useful in many consumer,  
automotive, computer peripheral, and battery-operated hand-held applications.  
There are three basic address spaces available to support a wide range of configurations:  
1. Program Memory  
2. Register File  
3. Expanded Register File  
The Register file is composed of 256 B of RAM. It includes three I/O port registers, 16  
control and status registers, and 237 general-purpose registers. The Expanded Register file  
consists of two additional register groups (F and D).  
To unburden the program from coping with such real-time problems like generating  
complex waveforms or receiving and demodulating complex waveform/pulses, the  
Crimzon ZLR16300 offers a new intelligent counter/timer architecture with 8-bit and  
16-bit counter/timers (see Figure 2 on page 4). Also included are a large number of  
user-selectable modes and two on-board comparators to process analog signals with  
separate reference voltages.

Pin Functions  
XTAL1 Crystal 1 (Time-Based Input)  
This pin connects a parallel-resonant crystal or ceramic resonator to the on-chip oscillator  
input. Additionally, an external single-phase clock can be connected to the on-chip  
oscillator input.  
XTAL2 Crystal 2 (Time-Based Output)  
This pin connects a parallel-resonant crystal or ceramic resonant to the on-chip oscillator  
output.  
Input/Output Ports  
Caution:  
The CMOS input buffer for each ports 0, 1, or 2 pin is always connected to the pin, even  
when the pin is configured as an output. If the pin is configured as an open-drain output  
and no external signal is applied, a High output state causes the CMOS input buffer to  
float. This leads to excessive leakage current of more than 100 A. To prevent this leakage,  
connect the pin to an external signal with a defined logic level or ensure its output state is  
Low, especially during STOP mode.  
Internal pull-ups are disabled on any given pin or group of port pins when programmed  
into output mode.  
Port 0, 1, and 2 have both input and output capability. The input logic is always present  
no matter whether the port is configured as input or output. While performing a READ  
instruction, the MCU reads the actual value at the input logic but not from the output  
buffer. In addition, the instructions of OR, AND, and XOR have the Read-Modify-Write  
sequence. The MCU first reads the port, modifies the value, and loads back to the port.  
Precaution must be taken if the port is configured as open-drain output or if the port is  
driving any circuit that makes the voltage different from the desired output logic. For  
example, pins P00–P07 are not connected to anything else. If it is configured as open-  
drain output with output logic as ONE, it is a floating port and reads back as ZERO. The  
following instruction sets P00-P07 all Low.

Port 0 (P07–P00)  
Port 0 is an 8-bit, bidirectional, and CMOS-compatible port. These eight I/O lines are con-  
figured under software control as a nibble I/O port. The output drivers are push-pull or  
open-drain controlled by bit D2 in the PCON register.  
If one or both nibbles are required for I/O operation, they must be configured by writing to  
the Port 0 mode register. After a hardware reset, Port 0 is configured (see Figure 5) as an  
input port.  
An optional pull-up transistor is available as a mask option on all Port 0 bits with nibble  
select.  
The Port 0 direction is reset to be input following an Stop Mode Recovery.

Port 2 (P27–P20)  
Port 2 is an 8-bit, bidirectional, and CMOS-compatible I/O port (see Figure 6). These  
eight I/O lines are independently configured under software control as inputs or outputs.  
Port 2 is always available for I/O operation. A mask option connects eight pull-up  
transistors on this port. Bits programmed as outputs are globally programmed as either  
push-pull or open-drain. The POR resets with the eight bits of Port 2 configured as inputs.  
Port 2 also has an 8-bit input OR and AND gate which can be used to wake up the part.  
P20 is programmed to access the edge-detection circuitry in DEMODULATION mode.

Port 3 (P37–P30)  
Port 3 is an 8-bit, CMOS-compatible fixed I/O port (see Figure 7). Port 3 consists of four  
fixed input (P33–P30) and four fixed output (P37–P34), which are configured under  
software control for interrupt and as output from the counter/timers. P30, P31, P32, and  
P33 are standard CMOS inputs; P34, P35, P36, and P37 are push-pull outputs.

Two on-board comparators process analog signals on P31 and P32, with reference to the  
voltage on Pref1 and P33. The analog function is enabled by programming the Port 3  
Mode Register (bit 1). P31 and P32 are programmable as rising, falling, or both edge  
triggered interrupts (IRQ register bits 6 and 7). Pref1 and P33 are the comparator reference  
voltage inputs. Access to the Counter Timer edge-detection circuit is through P31 or P20  
(see T8 and T16 Common Functions—CTR1(0D)01h on page 23). Other edge detect and  
IRQ modes are described in Table 5.  
Comparators are powered down by entering STOP mode. For P31–P33 to be used in a  
SMR source, these inputs must be placed into DIGITAL mode.

Comparator Inputs  
In ANALOG mode, P31 and P32 have a comparator front end. The comparator reference  
is supplied to P33 and PREF1. In this mode, the P33 internal data latch and its  
corresponding IRQ1 are diverted to the SMR sources (excluding P31, P32, and P33) as  
displayed in Figure 7 on page 10. In DIGITAL mode, P33 is used as D3 of the Port 3 input  
register, which then generates IRQ1.  
Comparators are powered down by entering STOP mode. For P31–P33 to be used in a  
Stop Mode Recovery source, these inputs must be placed into DIGITAL mode.  
Note:  
Comparator Outputs  
These channels are programmed to be output on P34 and P37 through the PCON register.

Expanded Register File  
The register file has been expanded to allow for additional system control registers and for  
mapping additional peripheral devices into the register address area. The Z8 register  
address space (0 through15 (OFh)) has been implemented as 16 banks, with 16 registers  
per bank. These register banks are known as the ERF (Expanded Register File). Bits 7–4  
of register RP select the working register group. Bits 3–0 of register RP select the  
expanded register file bank.  
An expanded register bank is also referred to as an expanded register group (see Figure 10  
on page 17).

The upper nibble of the register pointer (see Figure 11) selects which working register  
group, of 16 bytes in the register file, is accessed out of the possible 256. The lower nibble  
selects the expanded register file bank and in the case of the Crimzon ZLR16300 family,  
banks 0, F, and D are implemented. A 0hin the lower nibble allows the normal register  
file (bank 0) to be addressed. Any other value from 1hto Fhexchanges the lower 16 reg-  
isters to the selected expanded register bank.

Register File  
The Register file (bank 0) consists of three I/O port registers, 237 general-purpose regis-  
ters, 16 control and status registers (R0, R2, R3, R4–R239, and R240–R255, respectively),  
and two expanded register Banks D (see Table 6 on page 22) and F. Instructions can access  
registers directly or indirectly through an 8-bit address field, thereby allowing a short, 4-  
bit register address to use the Register Pointer (see Figure 12 on page 20). In the 4-bit  
mode, the register file is divided into 16 working register groups, each occupying 16 con-  
tinuous locations. The Register Pointer addresses the starting location of the active work-  
ing register group.  
Register address E0h–EFh can be accessed only through working registers and indirect  
addressing modes.

T8 Enable  
This field enables T8 when set to 1.  
Single/Modulo-N  
When set to 0 (MODULO-N), the counter reloads the initial value when the terminal  
count is reached. When set to 1 (Single-Pass), the counter stops when the terminal count is  
reached.  
Timeout  
This bit is set when T8 times out (terminal count reached). To reset this bit, write a 1 to its  
location.  
Writing a 1 is the only way to reset the Terminal Count status condition. Reset this bit  
before using/enabling the counter/timers.  
Caution:  
The first clock of T8 might not have complete clock width and can occur any time when  
enabled.  
Ensure to manipulate CTR0, bit 5 and CTR1, bits 0 and 1 (DEMODULATION mode)  
while using the OR or AND commands. These instructions use a Read-Modify-Write  
sequence in which the current status from the CTR0 and CTR1 registers is ORed or  
ANDed with the designated value and then written back into the registers.  
Note:  
T8 Clock  
These bits define the frequency of the input signal to T8.  
Capture_INT_Mask  
Set this bit to allow an interrupt when data is captured into either LO8 or HI8 upon a posi-  
tive or negative edge detection in CAPTURE Mode.  
Counter_INT_Mask  
Set this bit to allow an interrupt when T8 has a timeout.  
P34_Out  
This bit defines whether P34 is used as a normal output pin or the T8 output.

Mode  
If the result is 0, the counter/timers are in TRANSMIT mode, else, they are in DEMODU-  
LATION mode.  
P36_Out/Demodulator_Input  
In TRANSMIT mode, this bit defines whether P36 is used as a normal output pin or the  
combined output of T8 and T16.  
In DEMODULATION mode, this bit defines whether the input signal to the Counter/Tim-  
ers is from P20 or P31.  
If the input signal is from Port 31, a capture event generates an IRQ2 interrupt. To prevent  
generating an IRQ2, either disable the IRQ2 interrupt by clearing its IMR bit D2 or use  
P20 as the input.  
T8/T16_Logic/Edge_Detect  
In TRANSMIT mode, this field defines how the outputs of T8 and T16 are combined  
(AND, OR, NOR, NAND).  
In DEMODULATION mode, this field defines which edge is detected by the edge detec-  
tor.  
Transmit_Submode/Glitch Filter  
In TRANSMIT mode, this field defines whether T8 and T16 are in the PING-PONG mode  
or in independent Normal operation mode. Setting this field to ‘Normal Operation mode’  
terminates the ‘PING-PONG mode’ operation. When set to 10, T16 is immediately forced  
to a 0; a setting of 11 forces T16 to output a 1.  
In DEMODULATION mode, this field defines the width of the glitch that must be filtered  
out.

put of T8 is set to 1 when it starts to count. When the counter is not enabled and this bit is  
set to 1 or 0, T8_OUT is set to the opposite state of this bit. This ensures that when the  
clock is enabled, a transition occurs to the initial state set by CTR1, D1.  
In DEMODULATION mode, this bit is set to 1 when a rising edge is detected in the input  
signal. In order to reset the mode, a 1 should be written to this location.  
Initial_T16 Out/Falling _Edge  
In TRANSMIT mode, if it is 0, the output of T16 is set to 0 when it starts to count. If it is  
1, the output of T16 is set to 1 when it starts to count. This bit is effective only in NOR-  
MAL or PING-PONG mode (CTR1, D3; D2). When the counter is not enabled and this bit  
is set, T16_OUT is set to the opposite state of this bit. This ensures that when the clock is  
enabled, a transition occurs to the initial state set by CTR1, D0.  
In DEMODULATION mode, this bit is set to 1 when a falling edge is detected in the input  
signal. In order to reset it, a 1 should be written to this location.  
Modifying CTR1 (D1 or D0) while the counters are enabled causes unpredictable output  
from T8/16_OUT.

Input Circuit  
The edge detector monitors the input signal on P31 or P20. Based on CTR1 D5–D4, a  
pulse is generated at the Pos Edge or Neg Edge line when an edge is detected. Glitches in  
the input signal that have a width less than specified (CTR1 D3, D2) are filtered out (see  
Figure 13).

When T8 is enabled, the output T8_OUT switches to the initial value (CTR1, D1). If the  
initial value (CTR1, D1) is 0, TC8L is loaded, else, TC8H is loaded into the counter. In  
SINGLE-PASS mode (CTR0, D6), T8 counts down to 0 and stops, T8_OUT toggles, the  
timeout status bit (CTR0, D5) is set, and a timeout interrupt can be generated if it is  
enabled (CTR0, D1). In MODULO-N mode, upon reaching terminal count, T8_OUT is  
toggled, but no interrupt is generated. From that point, T8 loads a new count (if the  
T8_OUT level now is 0), TC8L is loaded; if it is 1, TC8H is loaded. T8 counts down to 0,  
toggles T8_OUT, and sets the timeout status bit (CTR0, D5), thereby generating an inter-  
rupt if enabled (CTR0, D1). One cycle is complete. T8 then loads from TC8H or TC8L  
according to the T8_OUT level and repeats the cycle. See Figure 15.

Using the same instructions for stopping the counter/timers and setting the status bits is  
not recommended.  
Caution:  
Two successive commands are necessary. First, the counter/timers must be stopped. Sec-  
ond, the status bits must be reset. These commands are required because it takes one coun-  
ter/timer clock interval for the initiated event to actually occur. See Figure 16 and

You must program TC8L and TC8H to FFh. After T8 is enabled, when the first edge (ris-  
ing, falling, or both depending on CTR1, D5; D4) is detected, it starts to count down.  
When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected  
during counting, the current value of T8 is complemented and put into one of the capture  
registers. If it is a positive edge, data is put into LO8; if it is a negative edge, data is stored  
in HI8. From that point, one of the edge detect status bits (CTR1, D1; D0) is set, and an  
interrupt is generated if enabled (CTR0, D2). Meanwhile, T8 is loaded with FFhand starts  
counting again. If T8 reaches 0, the timeout status bit (CTR0, D5) is set, and an interrupt

T16 TRANSMIT Mode  
In NORMAL or PING-PONG mode, the output of T16 when not enabled, is dependent on  
CTR1, D0. If it is a 0, T16_OUT is a 1; if it is a 1, T16_OUT is 0. You can force the output  
of T16 to either a 0 or 1 whether it is enabled or not by programming CTR1 D3; D2 to a  
10 or 11.  
When T16 is enabled, TC16H * 256 + TC16L is loaded, and T16_OUT is switched to its  
initial value (CTR1, D0). When T16 counts down to 0, T16_OUT is toggled (in NOR-  
MAL or PING-PONG mode), an interrupt (CTR2, D1) is generated (if enabled), and a sta-  
tus bit (CTR2, D5) is set. See Figure 20.

T16 DEMODULATION Mode  
You must program TC16L and TC16H to FFh. Once T16 is enabled, and the first edge  
(rising, falling, or both depending on CTR1 D5; D4) is detected, T16 captures HI16 and  
LO16, reloads, and begins counting.  
If D6 of CTR2 Is 0  
When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected  
during counting, the current count in T16 is complemented and put into HI16 and LO16.  
When data is captured, one of the edge detect status bits (CTR1, D1; D0) is set, and an  
interrupt is generated if enabled (CTR2, D2). T16 is loaded with FFFFhand starts again.  
This T16 mode is generally used to measure space time, the length of time between bursts  
of carrier signal (marks).  
19-4622; Rev 0; 5/09  
Functional Description  
Crimzon® ZLR16300  
Product Specification  
37  
If D6 of CTR2 Is 1  
T16 ignores the subsequent edges in the input signal and continues counting down. A  
timeout of T8 causes T16 to capture its current value and generate an interrupt if enabled  
(CTR2, D2). In this case, T16 does not reload and continues counting. If the D6 bit of  
CTR2 is toggled (by writing a 0 then a 1 to it), T16 captures and reloads on the next edge  
(rising, falling, or both depending on CTR1, D5; D4), continuing to ignore subsequent  
edges.  
This T16 mode generally measures mark time, the length of an active carrier signal burst.  
If T16 reaches 0, T16 continues counting from FFFFh. Meanwhile, a status bit (CTR2 D5)  
is set, and an interrupt timeout is generated if enabled (CTR2 D1).  
PING-PONG Mode  
This operation mode is valid only in TRANSMIT mode. T8 and T16 must be programmed  
in SINGLE-PASS mode (CTR0, D6; CTR2, D6), and Ping-Pong mode must be pro-  
grammed in CTR1, D3; D2. You can begin the operation by enabling either T8 or T16  
(CTR0, D7 or CTR2, D7). For example, if T8 is enabled, T8_OUT is set to this initial  
value (CTR1, D1). According to T8_OUT's level, TC8H or TC8L is loaded into T8. After  
the terminal count is reached, T8 is disabled, and T16 is enabled. T16_OUT then switches  
to its initial value (CTR1, D0), data from TC16H and TC16L is loaded, and T16 starts to  
count. After T16 reaches the terminal count, it stops, T8 is enabled again, repeating the  
entire cycle. Interrupts are allowed when T8 or T16 reaches terminal control (CTR0, D1;  
CTR2, D1). To stop the Ping-Pong operation, write 00 to bits D3 and D2 of CTR1. See  
Figure 23.  
Enabling Ping-Pong operation while the counter/timers are running might cause intermit-  
tent counter/timer function. Disable the counter/timers and reset the status Flags before  
instituting this operation.

The initial value of T8 or T16 must not be 1. If you stop the timer and restart the timer,  
reload the initial value to avoid an unknown previous value.  
During PING-PONG Mode  
The enable bits of T8 and T16 (CTR0, D7; CTR2, D7) are set and cleared alternately by  
hardware. The timeout bits (CTR0, D5; CTR2, D5) are set every time the counter/timers  
reach the terminal count.  
Timer Output  
The output logic for the timers is displayed in Figure 24. P34 is used to output T8-OUT  
when D0 of CTR0 is set. P35 is used to output the value of T16-OUT when D0 of CRTR2  
is set. When D6 of CTR1 is set, P36 outputs the logic combination of T8-OUT and T16-  
OUT determined by D5 and D4 of CTR1.

Interrupts  
The Crimzon ZLR16300 features six different interrupts (see Table 10 on page 41). The  
interrupts are maskable and prioritized (see Figure 25 on page 40). The six sources are  
divided as follows:  
Three sources are claimed by Port 3 lines P33–P31  
Two by the counter/timers (see Table 10 on page 41)  
One for low-voltage detection  
The Interrupt Mask Register (globally or individually) enables or disables the six interrupt  
requests.  
The source for IRQ is determined by bit 1 of the Port 3 mode register (P3M). When in  
DIGITAL mode, Pin P33 is the source. When in ANALOG mode the output of the Stop  
Mode Recovery source logic is used as the source for the interrupt. See Figure 30 on page  
47.

When more than one interrupt is pending, priorities are resolved by a programmable prior-  
ity encoder controlled by the Interrupt Priority Register. An interrupt machine cycle acti-  
vates when an interrupt request is granted. As a result, all subsequent interrupts are  
disabled, and the Program Counter and Status Flags are saved. The cycle then branches to  
the Program Memory vector location reserved for that interrupt. All Crimzon ZLR16300  
interrupts are vectored through locations in the Program Memory. This memory location  
and the next byte contain the 16-bit address of the interrupt service routine for that partic-  
ular interrupt request. To accommodate polled interrupt systems, interrupt inputs are  
masked, and the Interrupt Request register is polled to determine which of the interrupt  
requests require service.  
An interrupt resulting from AN1 is mapped into IRQ2, and an interrupt from AN2 is  
mapped into IRQ0. Interrupts IRQ2 and IRQ0 can be rising, falling, or both edge trig-  
gered. You can program these interrupts. The software can poll to identify the state of the  
pin.  
Programming bits for the Interrupt Edge Select are located in the IRQ Register (R250),  
bits D7 and D6. Table 11 indicates the IRQ configuration.

Clock  
The device’s on-chip oscillator has a high-gain, parallel-resonant amplifier for connection  
to a crystal, ceramic resonator, or any suitable external clock source (XTAL1 = Input,  
XTAL2 = Output). The crystal must be AT cut, 1 MHz to 8 MHz (maximum) with a series  
resistance (RS) less than or equal to 100 . The on-chip oscillator is driven with a suitable  
external clock source.  
The crystal must be connected across XTAL1 and XTAL2 using the recommended capac-  
itors from each pin to ground. The typical capacitor value is 10 pF for 8 MHz.  
Check with the crystal supplier for the optimum capacitance.

Figure 26. Oscillator Configuration  
Maxim’s IR MCU supports crystal, resonator, and oscillator. Most resonators have a fre-  
quency tolerance of less than ±0.5%, which is enough for remote control application. Res-  
onator has a very fast startup time, which is around few hundred microseconds. Most  
crystals have a frequency tolerance of less than 50 ppm (±0.005%). However, crystal  
needs longer startup time than the resonator. The large loading capacitance slows down  
the oscillation startup time. Maxim suggests not to use more than 10 pF loading capacitor  
for the crystal. If the stray capacitance of the PCB or the crystal is high, the loading capac-  
itance C1 and C2 must be reduced further to ensure stable oscillation before the TPOR  
(Power-On Reset time is typically 5–6 ms, see Table 18 on page 75).  
For SMR operation, bit 5 of SMR register allows you to select the SMR delay, which is the  
TPOR. If SMR delay is not selected, the MCU executes instruction immediately after it  
wakes up from the STOP mode. If resonator or crystal is used as a clock source then SMR  
delay needs to be selected (bit 5 of SMR = 1).

For both resonator and crystal oscillator, the oscillation ground must go directly to the  
ground pin of the microcontroller. The oscillation ground must use the shortest distance  
from the microcontroller ground pin and it must be isolated from other connections.  
Power Management  
Power-On Reset  
A timer circuit clocked by a dedicated on-board RC-oscillator is used for the Power-On  
Reset timer function. The POR time allows VDD and the oscillator circuit to stabilize  
before instruction execution begins.  
The POR timer circuit is a one-shot timer triggered by one of three conditions:  
1. Power Fail to Power OK status, including Waking up from VBO Standby.  
2. Stop Mode Recovery (if D5 of SMR = 1).  
3. WDT Timeout.  
The POR timer is 2.5 ms minimum. Bit 5 of the Stop-Mode Register determines whether  
the POR timer is bypassed after Stop Mode Recovery (typical for external clock).  
HALT Mode  
This instruction turns Off the internal CPU clock, but not the XTAL oscillation. The coun-  
ter/timers and external interrupts IRQ0, IRQ1, IRQ2, IRQ3, IRQ4, and IRQ5 remain  
active. The devices are recovered by interrupts, either externally or internally generated.  
An interrupt request must be executed (enabled) to exit HALT mode. After the interrupt  
service routine, the program continues from the instruction after the HALT.  
STOP Mode  
This instruction turns OFF the internal clock and external crystal oscillation, reducing the  
standby current to 10 A or less. STOP mode is terminated only by a reset, such as WDT  
timeout, POR or SMR. This condition causes the processor to restart the application pro-  
gram at address 000Ch. In order to enter STOP (or HALT) mode, first flush the instruction  
pipeline to avoid suspending execution in mid-instruction. Execute an NOP instruction  
(Opcode = FFh) immediately before the appropriate sleep instruction, as follows:  
FF  
6F  
NOP  
STOP  
; clear the pipeline  
; enter Stop Mode  
or

Any Port 2 bit defined as an output drives the corresponding input to the default state. This  
condition allows the remaining inputs to control the AND/OR function. For other recover  
sources, see Stop Mode Recovery Register 2 (SMR2).  
Note:  
Stop Mode Recovery Delay Select (D5)  
This bit, if Low, disables the TPOR delay after Stop Mode Recovery. The default configu-  
ration of this bit is 1. If the ‘fast’ wake-up is selected, the Stop Mode Recovery source  
must be kept active for at least 10 TpC.  
This bit must be set to 1 if using a crystal or resonator clock source. The TPOR delay  
allows the clock source to stabilize before executing instructions.  
Note:  
Stop Mode Recovery Edge Select (D6)  
A 1 in this bit position indicates that a High level on any one of the recovery sources  
wakes the Crimzon ZLR16300 from STOP mode. A 0 indicates Low level recovery. The  
default is 0 on POR.  
Cold or Warm Start (D7)  
This bit is read only. It is set to 1 when the device is recovered from STOP mode. The bit  
is set to 0 when the device reset is other than SMR.

Watchdog Timer Mode  
Watchdog Timer Mode Register (WDTMR)  
The Watchdog Timer is a retriggerable one-shot timer that resets the Z8 if it reaches its ter-  
minal count. The WDT must initially be enabled by executing the WDT instruction. On  
subsequent executions of the WDT instruction, the WDT is refreshed. The WDT circuit is  
driven by an on-board RC-oscillator. The WDT instruction affects the Zero (Z), Sign (S),  
and Overflow (V) Flags.  
The POR clock source the internal RC-oscillator. Bits 0 and 1 of the WDT register control  
a tap circuit that determines the minimum timeout period. Bit 2 determines whether the  
WDT is active during HALT, and Bit 3 determines WDT activity during STOP. Bits 4  
through 7 are reserved (see Figure 32). This register is accessible only during the first 60  
processor cycles (120 XTAL clocks) from the execution of the first instruction after  
Power-On Reset, Watchdog Reset, or a Stop Mode Recovery (see Figure 31 on page 49).  
After this point, the register cannot be modified by any means (intentional or otherwise).  
The WDTMR cannot be read. The register is located in Bank F of the Expanded Register  
File at address location 0Fh. It is organized as displayed in Figure 32.

Voltage Brownout/Standby  
An on-chip Voltage Comparator checks that the VDD is at the required level for correct  
operation of the device. Reset is globally driven when VDD falls below VBO. A small drop  
in VDD causes the XTAL1 and XTAL2 circuitry to stop the crystal or resonator clock. If  
the VDD is allowed to stay above VRAM, the RAM content is preserved. When the power  
level is returned to above VBO, the device performs a POR and functions normally.

Voltage Detection and Flags  
The Voltage Detection register (LVD, register 0Ch at the expanded register bank 0Dh)  
offers an option of monitoring the VCC voltage. The Voltage Detection is enabled when bit  
0 of LVD register is set. When Voltage Detection is enabled, the VCC level is monitored in  
real time. The Flags in the LVD register valid 20 us after Voltage Detection is enabled.  
The HVD Flag (bit 2 of the LVD register) is set only if VCC is lower than the VHVD. When  
Voltage Detection is enabled, the LVD Flag also triggers IRQ5. The IRQ bit 5 latches the  
low-voltage condition until it is cleared by instructions or reset. The IRQ5 interrupt is  
served if it is enabled in the IMR register. Otherwise, bit 5 of IRQ register is latched as a  
Flag only.  
If it is necessary to receive an LVD interrupt upon power-up at an operating voltage lower  
than the low battery detect threshold, enable interrupts using the Enable Interrupt instruc-  
tion (EI) prior to enabling the voltage detection.
