■ DIFFERENCES AMONG PRODUCTS

1. Memory Size

Before evaluating using the piggyback product, verify its differences from the product that will actually be used.

Take particular care on the following points:

• On the MB89821, the register bank address upper than 0140H cannot be used. On the MB89823R, MB89825

and MB89P825, each register bank addresses upper than 0180H can be used.

• On the MB89P825, addresses BFF0H to BFF6H comprise the option setting area, option settings can be read

by reading these addresses.

• The stack area, etc., is set at the upper limit of the RAM.

2. Current Consumption

• In the case of the MB89PV820, add the current consumed by the EPROM which is connected to the top socket.

• However, the current consumption in sleep/stop modes is the same. (For more information, see section

“■ Electrical Characteristics.”

3. Mask Options

Functions that can be selected as options and how to designate these options vary by the product.

Before using options check section “■ Mask Options.”

■ HANDLING DEVICES

1. Preventing Latchup

Latchup may occur on CMOS ICs if voltage higher than VCC or lower than VSS is applied to input and output pins

other than medium- to high-voltage pins or if higher than the voltage which shows on “1. Absolute Maximum

Ratings” in section “■ Electrical Characteristics” is applied between VCC and VSS.

When latchup occurs, power supply current increases rapidly and might thermally damage elements. When

using, take great care not to exceed the absolute maximum ratings.

Also, take care to prevent the analog power supply (AV^CCand AVR) and analog input from exceeding the digital

power supply (VCC) when the analog system power supply is turned on and off.

2. Treatment of Unused Input Pins

Leaving unused input pins open could cause malfunctions. They should be connected to a pull-up or pull-down

resistor.

3. Treatment of Power Supply Pins on Microcontrollers with A/D and D/A Converters

Connect to be AVCC = DAVC = VCC and AVSS = AVR = VSS even if the A/D and D/A converters are not in use.

4. Treatment of N.C. Pins

Be sure to leave (internally connected) N.C. pins open.

5. Power Supply Voltage Fluctuations

Although VCC power supply voltage is assured to operate within the rated range, a rapid fluctuation of the voltage

could cause malfunctions, even if it occurs within the rated range. Stabilizing voltage supplied to the IC is therefore

important. As stabilization guidelines, it is recommended to control power so that VCC ripple fluctuations (P-P

value) will be less than 10% of the standard VCC value at the commercial frequency (50 to 60 Hz) and the transient

fluctuation rate will be less than 0.1 V/ms at the time of a momentary fluctuation such as when power is switched.

6. Precautions when Using an External Clock

Even when an external clock is used, oscillation stabilization time is required for power-on reset (optional) and

wake-up from stop mode.

7. Note to Noise In the External Reset Pin (RST)

If the reset pulse applied to the external reset pin (RST) does not meet the specifications, it may cause malfunc-

tions. Use caution so that the reset pulse less than the specifications will not be fed to the external reset pin (RST) .

3. Programming to the EPROM

In EPROM mode, the MB89P825 functions equivalent to the MBM27C256A. This allows the PROM to be

programmed with a general-purpose EPROM programmer (the electronic signature mode cannot be used) by

using the dedicated socket adapter.

•

Programming procedure

(1) Set the EPROM programmer to the MBM27C256A.

(2) Load program data into the EPROM programmer at 4000^Hto 7FFFH (note that addresses C000H to FFFFH

while operating as a single chip assign to 4000H to 7FFFH in EPROM mode).

Load option data into addresses 3FF0H to 3FF5H of the EPROM programmer. (For information about each

corresponding option, see “7. OTPROM Option Bit Map.”

(3) Program with the EPROM programmer.

■ CPU CORE

1. Memory Space

The microcontrollers of the MB89820 series offer a memory space of 64 Kbytes for storing all of I/O, data, and

program areas. The I/O area is located at the lowest address. The data area is provided immediately above the

I/O area. The data area can be divided into register, stack, and direct areas according to the application. The

program area is located at exactly the opposite end, that is, near the highest address. Provide the tables of

interrupt reset vectors and vector call instructions toward the highest address within the program area. The

memory space of the MB89820 series is structured as illustrated below.

2. Registers

The F²MC-8L family has two types of registers; dedicated registers in the CPU and general-purpose registers

in the memory. The following dedicated registers are provided:

Program counter (PC):

Accumulator (A):

A 16-bit register for indicating instruction storage positions

A 16-bit temporary register for storing arithmetic operations, etc. When the

instruction is an 8-bit data processing instruction, the lower byte is used.

Temporary accumulator (T): A 16-bit register which performs arithmetic operations with the accumulator

When the instruction is an 8-bit data processing instruction, the lower byte is used.

Index register (IX):

Extra pointer (EP):

Stack pointer (SP):

Program status (PS):

A 16-bit register for index modification

A 16-bit pointer for indicating a memory address

A 16-bit register for indicating a stack area

A 16-bit register for storing a register pointer, a condition code

The CCR consists of bits indicating the results of arithmetic operations and the contents of transfer data and

bits for control of CPU operations at the time of an interrupt.

H-flag : Set when a carry or a borrow from bit 3 to bit 4 occurs as a result of an arithmetic operation. Cleared

otherwise. This flag is for decimal adjustment instructions.

I-flag : Interrupt is allowed when this flag is set to 1. Interrupt is prohibited when the flag is set to 0. Set to 0

when reset.

IL1, 0 : Indicates the level of the interrupt currently allowed. Processes an interrupt only if its request level is

higher than the value indicated by this bit.

N-flag : Set if the MSB is set to 1 as the result of an arithmetic operation. Cleared when the bit is set to 0.

Z-flag : Set when an arithmetic operation results in 0. Cleared otherwise.

V-flag : Set if the complement on 2 overflows as a result of an arithmetic operation. Reset if the overflow does not

occur.

C-flag : Set when a carry or a borrow from bit 7 occurs as a result of an arithmetic operation. Cleared otherwise.

Set to the shift-out value in the case of a shift instruction.

MB89820 Series

The following general-purpose registers are provided:

General-purpose registers: An 8-bit register for storing data

The general-purpose registers are 8 bits and located in the register banks of the memory. One bank contains

eight registers and up to a total of 16 banks can be used on the MB89823R/825 (RAM 256 × 8 bits). The bank

currently in use is indicated by the register bank pointer (RP).

NoteThe number of register banks that can be used varies with the RAM size.

*1: The oscillation settling time is generated by dividing the oscillation clock frequency. Since the oscillation period

is not stable immediately after oscillation has been started, therefore, the oscillation settling time in the above

list should be regarded as a reference.

*2: Port selection must be same setting of the segment output selection register of LCD controller.

*3: Note that, when ports are set, the input voltage value for the port pins are different from those for mask ROM

products.

Ports are set by the register setting of the segment output selection register of LCD controller.
