■ DIFFERENCES AMONG PRODUCTS

Memory Size

In evaluation with an evaluation product, note the difference between the evaluation product and the product

actually used. The following items must be taken into consideration.

• The MB90V570A does not have an internal ROM, however, operations equivalent to chips with an internal

ROM can be evaluated by using a dedicated development tool, enabling selection of ROM size by settings of

the development tool.

• In the MB90V570A, images from FF4000^Hto FFFFFFH are mapped to bank 00, and FE0000H to FF3FFFH to

mapped to bank FE and FF only. (This setting can be changed by configuring the development tool.)

• In the MB90573/574C/F574A, images from FF4000^Hto FFFFFFH are mapped to bank 00, and FF0000H to

FF3FFF^Hto bank FF only.

• The products designated with /A or /C are different from those without /A or /C in that they are DTP/externally-

interrupted types which return from standby mode at the ch.0 to ch.1 edge request.

■ HANDLING DEVICES

1. Preventing Latchup

CMOS ICs may cause latchup in the following situations:

• When a voltage higher than Vcc or lower than Vss is applied to input or output pins.

• When a voltage exceeding the rating is applied between Vcc and Vss.

• When AVcc power is supplied prior to the Vcc voltage.

In turning on/turning off the analog power supply, make sure the analog power voltage (AV^CC, AVRH, DVCC)and

analog input voltages not exceed the digital voltage (V^CC).

2. Treatment of unused pins

Leaving unused input pins open may result in misbehavior or latch up and possible permanent damage of the

device. Therefor they must be tied to V^CCor Ground through resistors. In this case those resistors should be

more than 2 kΩ.

Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above

described connection.

3. Notes on Using External Clock

In using the external clock, drive X0 pin only and leave X1 pin unconnected.

• Using external clock

Open

4. Unused Sub Clock Mode

If sub clock modes are not used, the oscillator should be connected to the X01A pin and X1A pin

5. Power Supply Pins (VCC/VSS)

In products with multiple VCC or VSS pins, the pins of a same potential are internally connected in the device to

avoid abnormal operations including latch-up. However, connect the pins external power and ground lines to

lower the electro-magnetic emission level, to prevent abnormal operation of strobe signals caused by the rise

in the ground level, and to conform to the total current rating.

Make sure to connect V^CCand VSS pins via lowest impedance to power lines.

16

DS07-13701-9E

MB90570A/570C Series

It is recommended to provide a bypass capacitor of around 0.1 µF between VCC and VSS pin near the device.

6. Crystal Oscillator Circuit

Noises around X0 or X1 pins may be possible causes of abnormal operations. Make sure to provide bypass

capacitors via shortest distance from X0, X1 pins, crystal oscillator (or ceramic resonator) and ground lines, and

make sure, to the utmost effort, that lines of oscillation circuit do not cross the lines of other circuits.

It is highly recommended to provide a printed circuit board art work surrounding X0 and X1 pins with an grand

area for stabilizing the operation.

Please ask the crystal maker to evaluate the oscillational characteristics of the crystal and this device.

7. Turning-on Sequence of Power Supply to A/D Converter and Analog Inputs

Make sure to turn on the A/D converter power supply, D/A converter power supply (AVCC, AVRH, AVRL,

DV^CC,DVSS) and analog inputs (AN0 to AN7) after turning-on the digital power supply (VCC).

Turn-off the digital power after turning off the A/D converter supply and analog inputs. In this case, make sure

that the voltage does not exceed AVRH or AV^CC(turning on/off the analog and digital power supplies simulta-

neously is acceptable).

8. Connection of Unused Pins of A/D Converter

Connect unused pins of A/D converter to AVCC = VCC, AVSS = AVRH = DVCC = VSS.

9. N.C. Pins

The N.C. (internally connected) pins must be opened for use.

10. Notes on Energization

To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at 50

or more µs (0.2 V to 2.7 V).

11. Indeterminate outputs from ports 0 and 1

The outputs from ports 0 and 1 become indeterminate during oscillation setting time of step-down circuit (during

a power-on reset) after the power is turned on. (MB90573, MB90V570A)

DS07-13701-9E

17

MB90570A/570C Series

The series without built-in step-down circuit have no oscillation setting time of step-down circuit, so outputs

should not become indeterminate. (MB90F574A,MB90574C)

*2: Oscillation setting time

2¹⁸/oscillation clock frequency (oscillation clock frequency of 16 MHz: 16.38 ms)

12. Initialization

In the device, there are internal registers which are initialized only by a power-on reset. Turn on the power again

to initialize these registers.

13. Return from standby state

If the power-supply voltage goes below the standby RAM holding voltage in the standby state, the device may

fail to return from the standby state. In this case, reset the device via the external reset pin to return to the normal

state.

14. Precautions for Use of ’DIV A, Ri,’ and ’DIVW A, Ri’ Instructions

The signed multiplication-division instructions ’DIV A, Ri,’ and ’DIVW A, RWi’ should be used when the corre-

sponding bank registers (DTB, ADB, USB, SSB) are set to value ’00h.’ If the corresponding bank registers (DTB,

ADB, USB, SSB) are set to a value other than ’00h,’ then the remainder obtained after the execution of the

instruction will not be placed in the instruction operand register.

15. Precautions for Use of REALOS

Extended intelligent I/O service (EI²OS) cannot be used, when REALOS is used.

16. Caution on PLL Clock Mode

If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even

when there is no external oscillator or external clock input is stopped. Performance of this operation, however,

cannot be guaranteed.

*: Addresses #1, #2 and #3 are unique to the product type.

Note : The ROM data of bank FF is reflected in the upper address of bank 00, realizing effective use of the C

compiler small model. The lower 16-bit of bank FF and the lower 16-bit of bank 00 is assigned to the same

address, enabling reference of the table on the ROM without stating “far”.

For example, if an attempt has been made to access 00C000^H, the contents of the ROM at FFC000H are

accessed actually. Since the ROM area of the FF bank exceeds 48 kbytes, the whole area cannot be reflected

in the image for the 00 bank. The ROM data at FF4000^Hto FFFFFFH looks, therefore, as if it were the image

for 00400^Hto 00FFFFH. Thus, it is recommended that the ROM data table be stored in the area of FF4000H

to FFFFFF^H.

*2 : For details of the RAM area, see “■ MEMORY MAP”.

*3 : The reserved area is disabled because it is used in the system.

Notes : • For bits that is initialized by an reset operation, the initial value set by the reset operation is listed as an

initial value. Note that the values are different from reading results.

ForLPMCR/CKSCR/WDTC, there are caseswhereinitializationisperformedornotperformed, depending

on the types of the reset. However initial value for resets that initializes the value are listed.

• The addresses following 0000FF^Hare reserved. No external bus access signal is generated.

• Boundary ####^Hbetween the RAM area and the reserved area varies with the product model.

■ PERIPHERALS

1. I/O Port

(1) Input/output Port

Port 0 through 4, 6, 8, A and B are general-purpose I/O ports having a combined function as an external bus

pin and a resource input. Port 0 to Port 3 have a general-purpose I/O ports function only in the single-chip mode.

• Operation as output port

The pin is configured as an output port by setting the corresponding bit of the DDR register to “1”.

Writing data to PDR register when the port is configured as output, the data is retained in the output latch in

the PDR and directly output to the pin.

The value of the pin (the same value retained in the output latch of PDR) can be read out by reading the PDR

register.

Note : When a read-modify-write instruction (e.g. bit set instruction) is performed to the port data register, the

destination bit of the operation is set to the specified value, not affecting the bits configured by the DDR

register for output, however, values of bits configured by the DDR register as inputs are changed because

input values to the pins are written into the output latch. To avoid this situation, configure the pins by the DDR

register as output after writing output data to the PDR register when configuring the bit used as input as

outputs.

• Operation as input port

The pin is configured as an input by setting the corresponding bit of the DDR register to “0”.

When the pin is configured as an input, the output buffer is turned-off and the pin is put into a high-impedance

status.

When a data is written into the PDR register, the data is retained in the output latch of the PDR, but pin outputs

are unaffected.

Reading the PDR register reads out the pin level (“0” or “1”).

2. Timebase Timer

The timebase timer is a 18-bit free run counter (timebase counter) for counting up in synchronization to the

internal count clock (divided-by-2 of oscillation) with an interval timer function for selecting an interval time from

four types of 2¹²/HCLK, 2¹⁴/HCLK, 2¹⁶/HCLK, and 2¹⁹/HCLK.

The timebase timer also has a function for supplying operating clocks for the timer output for the oscillation

stabilization time or the watchdog timer etc.

4. 8/16-bit PPG Timer

The 8/16-bit PPG timer is a 2-CH reload timer module for outputting pulse having given frequencies/duty ratios.

The two modules performs the following operation by combining functions.

• 8-bit PPG output 2-CH independent operation mode

This is a mode for operating independent 2-CH 8-bit PPG timer, in which PPG0 and PPG1 pins correspond

to outputs from PPG0 and PPG1 respectively.

• 16-bit PPG timer output operation mode

In this mode, PPG0 and PPG1 are combined to be operated as a 1-CH 8/16-bit PPG timer operating as a 16-

bit timer. Because PPG0 and PPG1 outputs are reversed by an underflow from PPG1 outputting the same

output pulses from PPG0 and PPG1 pins.

• 8 + 8-bit PPG timer output operation mode

In this mode, PPG0 is operated as an 8-bit communications prescaler, in which an underflow output of PPG0

is used as a clock source for PPG1. A toggle output of PPG0 and PPG output of PPG1 are output from PPG0

and PPG1 respectively.

• PPG output operation

A pulse wave with any period/duty ratio is output. The module can also be used as a D/A converter with an

external add-on circuit.

5. 16-bit I/O timer

The 16-bit I/O timer module consists of one 16-bit free run timer, two input capture circuits, and four output

comparators. This module allows two independent waveforms to be output on the basis of the 16-bit free run

timer. Input pulse width and external clock periods can, therefore, be measured.

(1) 16-bit free run Timer

The 16-bit free run timer consists of a 16-bit up counter, a control register, and a communications prescaler

register. The value output from the timer counter is used as basic timer (base timer) for input capture (ICU) and

output compare (OCU).

• A counter operation clock can be selected from four internal clocks (φ/4, φ/16, φ/32 and φ/64).

• An interrupt can be generated by overflow of counter value or compare match with OCU compare register 0.

(Compare match requires mode setup.)

• The counter value can be initialized to “0000^H” by a reset, software clear or compare match with OCU compare

register 0.

(2) Input Capture (ICU)

The input capture (ICU) generates an interrupt request to the CPU simultaneously with a storing operation of

current counter value of the 16-bit free run timer to the ICU data register (IPCP) upon an input of a trigger edge

to the external pin.

There are four sets (four channels) of the input capture external pins and ICU data registers, enabling measure-

ments of maximum of four events.

• The input capture has two sets of external input pins (IN0, IN1) and ICU registers (IPCP), enabling measure-

ments of maximum of four events.

• A trigger edge direction can be selected from rising/falling/both edges.

• The input capture can be set to generate an interrupt request at the storage timing of the counter value of the

16-bit free run timer to the ICU data register (IPCP).

(3) Output Compare (OCU)

The output compare (OCU) is two sets of compare units consisting of four-channel OCU compare registers, a

comparator and a control register.

An interrupt request can be generated for each channel upon a match detection by performing time-division

comparison between the OCU compare data register setting value and the counter value of the 16-bit free run

timer.

The OUT pin can be used as a waveform output pin for reversing output upon a match detection or a general-

purpose output port for directly outputting the setting value of the CMOD bit.

10. DTP/External Interrupt Circuit

DTP (Data Transfer Peripheral), which is located between the peripheral circuit outside the device and the

F²MC-16LX CPU, receives an interrupt request or DMA request generated by the external peripheral circuit* for

transmission to the F²MC-16LX CPU. DTP is used to activate the intelligent I/O service or interrupt processing.

As request levels for IRQ2 to IRQ7, two types of “H” and “L” can be selected for the intelligent I/O service. Rising

and falling edges as well as “H” and “L” can be selected for an external interrupt request. For IRQ0 and IRQ1,

a request by a level cannot be entered, but both edges can be entered.

* : The external peripheral circuit is connected outside the MB90570A/570C series device.

Note : IRQ0 and IRQ1 cannot be used for the intelligent I/O service and return from an interrupt.

11. Delayed Interrupt Generation Module

The delayed interrupt generation module generates interrupts for switching tasks for development on a real-time

operating system (REALOS series). The module can be used to generate softwarewise generates hardware

interrupt requests to the CPU and cancel the interrupts.

This module does not conform to the extended intelligent I/O service (EI²OS).

The DIRR is the register used to control delay interrupt request generation/cancellation. Programming this

register with “1” generates a delay interrupt request. Programming this register with “0” cancels a delay interrupt

request. Upon a reset, an interrupt is canceled. The reserved bit area can be programmed with either “0” or “1”.

For future extension, however, it is recommended that bit set and clear instructions be used to access this register.

12. 8/10-bit A/D Converter

The 8/10-bit A/D converter has a function of converting analog voltage input to the analog input pins (input

voltage) to digital values (A/D conversion) and has the following features.

• Minimum conversion time: 26.3 µs (at machine clock of 16 MHz, including sampling time)

• Minimum sampling time: 4 µs/256 µs (at machine clock of 16 MHz)

• Compare time: 176/352 machine cycles per channel (176 machine cycles are used for a machine clock below

8 MHz.)

• Conversion method: RC successive approximation method with a sample and hold circuit.

• 8-bit or 10-bit resolution

• Analog input pins: Selectable from eight channels by software

Single conversion mode: Selects and converts one channel.

Scan conversion mode:Converts two or more successive channels. Up to eight channels can be programmed.

Continuous conversion mode: Repeatedly converts specified channels.

Stop conversion mode:Stops conversion after completing a conversion for one channel and wait for the next

activation (conversion can be started synchronously.)

• Interrupt requests can be generated and the extended intelligent I/O service (EI²OS) can be started after the

end of A/D conversion. Furthermore, A/D conversion result data can be transferred to the memory, enabling

efficient continuous processing.

• When interrupts are enabled, there is no loss of data even in continuous operations because the conversion

data protection function is in effect.

• Starting factors for conversion: Selected from software activation, and external trigger (falling edge).

17. Address Match Detection Function

When the address is equal to a value set in the address detection register, the instruction code loaded into the

CPU is replaced forcibly with the INT9 instruction code (01H). As a result, when the CPU executes a set

instruction, the INT9 instruction is executed. Processing by the INT#9 interrupt routine allows the program

patching function to be implemented.

Two address detection registers are supported. An interrupt enable bit is prepared for each register. If the value

set in the address detection register matches an address and if the interrupt enable bit is set at “1”, the instruction

code loaded into the CPU is replaced forcibly with the INT9 instruction code.

19. Low-power Consumption (Standby) Mode

The F²MC-16LX has the following CPU operating mode configured by selection of an operating clock and clock

operation control.

• Clock mode

PLL clock mode: A mode in which the CPU and peripheral equipment are driven by PLL-multiplied oscillation

clock (HCLK).

Main clock mode:A mode in which the CPU and peripheral equipment are driven by divided-by-2 of the oscil

lation clock (HCLK).

The PLL multiplication circuits stops in the main clock mode.

• CPU intermittent operation mode

The CPU intermittent operation mode is a mode for reducing power consumption by operating the CPU

intermittently while external bus and peripheral functions are operated at a high-speed.

• Hardware standby mode

The hardware standby mode is a mode for reducing power consumption by stopping clock supply to the CPU

by the low-power consumption control circuit, stopping clock supplies to the CPU and peripheral functions

(timebase timer mode), and stopping oscillation clock (stop mode, hardware standby mode). Of these modes,

modes other than the PLL clock mode are power consumption modes.

Sudden changes in the power supply voltage may cause a power-on reset.

To change the power supply voltage while the device is in operation, it is recommended to raise the voltage

smoothly to suppress fluctuations as shown below.

In this case, change the supply voltage with the PLL clock not used. If the voltage drop is 1 V/s or fewer per sec-

ond, however, you can use the PLL clock.

6. A/D Converter Glossary

Resolution: Analog changes that are identifiable with the A/D converter

Linearity error:The deviation of the straight line connecting the zero transition point (“00 0000 0000” ↔ “00 0000

0001”) with the full-scale transition point (“11 1111 1110” ↔ “11 1111 1111”) from actual con-

version characteristics

Differential linearity error:The deviation of input voltage needed to change the output code by 1 LSB from the

theoretical value

Total error:The total error is defined as a difference between the actual value and the theoretical value, which

includes zero-transition error/full-scale transition error and linearity error.

7. Notes on Using A/D Converter

Select the output impedance value for the external circuit of analog input according to the following conditions.

Output impedance values of the external circuit MB90V570A/573 are 5 kΩ or lower, MB90F574A/574C are 10

kΩ or lower are recommended.

When capacitors are connected to external pins, the capacitance of several thousand times the internal capacitor

value is recommended to minimized the effect of voltage distribution between the external capacitor and internal

capacitor.

When the output impedance of the external circuit is too high, the sampling period for analog voltages may not

be sufficient (sampling period = 4.00 µs @machine clock of 16 MHz).

Note : Listed values must be considered as standards.

• Error

The smaller the | AVRH – AVRL |, the greater the error would become relatively.
