I/O Name and Function
Input Nonmaskable interrupt: Requests a
nonmaskable interrupt
Input Interrupt request 4 to 0: Maskable interrupt
request pins
Output Address bus: Outputs address signals
Input/ Data bus: Bidirectional data bus
output
Output Address strobe: Goes low to indicate valid
address output on the address bus
Output Read: Goes low to indicate reading from the
external address space
Output High write: Goes low to indicate writing to the
external address space; indicates valid data on
the data bus.
Input
Wait: Requests insertion of wait states in bus
cycles during access to the external address
space
Input Clock input A to D: External clock inputs
