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 from the H8/3003
bus has been granted to an external bus
master
Nonmaskable interrupt: Requests a
nonmaskable interrupt
Interrupt request 7 to 0: Maskable interrupt
request pins
Data bus: Bidirectional data bus
