Name and function
Data bus: 8-Bit bidirectional data bus.
Wait: Requests the CPU to insert T
when an off-chip address is accessed.
Read: Goes Low to indicate that the CPU is reading an external
address.
Write: Goes Low to indicate that the CPU is writing to an
external address.
Address Strobe: Goes Low to indicate that there is a valid
address on the address bus.
I/O Select: Goes Low when the CPU accesses addresses H’FF00
to H’FFFF. Can be used as a chip select signal replacing the upper
8 bits of the address bus when external devices are mapped onto
addresses H’FF80 to H’FF8F and H’FFA8 to H’FFAF.
NonMaskable Interrupt: Highest-priority interrupt request.
The NMIEG bit in the system control register determines whether
the interrupt is requested on the rising or falling edge of the NMI
input.
Interrupt Request 0 to 7: Maskable interrupt request pins.
Mode: Input pins for setting the MCU operating mode
according to the table below.

The inputs at these pins are latched in mode select bits 1 to 0
(MDS1 and MDS0) of the mode register (MDCR) on the rising
edge of the RES signal.
