I
MPU
For an 80-system parallel bus interface, serves as a
write strobe signal and writes data at the low level.
For a 68-system parallel bus interface, serves as an
enable signal to activate data read/write operation.
Inputs the serial transfer clock for a serial interface.
Fetches data at the rising edge of a clock.
RW/RD*/

1
I or
I/O
MPU
For an 80-system parallel bus interface, serves as a
write strobe signal and reads data at the low level.
For a 68-system parallel bus interface, serves as a
signal to select data read/write operation.
Low: Write High: Read
Serves as the bidirectional serial transfer data for a
serial interface. Sends/Receives data.
