I
MPU
For a 68-system bus interface, serves as an enable
signal to activate data read/write operation.
For an 80-system bus interface, serves as a write
strobe signal and writes data at the low level.
For an I2C bus or clock synchronized serial interface,
inputs the serial transfer clock.
RW/RD*/
SDA
1
I
MPU
For a 68-system bus interface, serves as a signal to
select data read/write operation. (Low: Write, High:
Read)
For an 80-system bus interface, serves as a read
strobe signal and reads data at the low level.
For an I2C bus or clock synchronized serial interface,
serves as the bi-directional serial transfer data.
Sends/Receives data.
DB0-DB15

I/O
MPU
Serves as a 16-bit bidirectional data bus.
For an 8-bit bus interface, data transfer uses DB15-
DB8; fix unused DB7-DB0 to the Vcc or GND level.
When I2C or clock synchronized serial interface is
used, fix DB0-DB15 to the Vcc or GND level.
