Reset input: When driven low, this pin
resets the chip
Reset output: For the mask ROM version,
outputs a reset signal to external devices
Also used as a power supply for on-board
programming of the flash memory version
with dual power supply.
Write enable signal: Write-control signal
for writing to flash memory for the flash
memory version with single power supply
Standby: When driven low, this pin forces a
transition to hardware standby mode
Bus request: Used by an external bus
master to request the bus right
Bus request acknowledge: Indicates that
the bus has been granted to an external bus
master
Nonmaskable interrupt: Requests a
nonmaskable interrupt
Interrupt request 5 to 0: Maskable
interrupt request pins
Address bus: Outputs address signals
Data bus: Bidirectional data bus
