Wait: Requests the CPU to insert wait
states into the bus cycle when an external
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.
Nonmaskable interrupt: Highest-priority
interrupt request. The NMIEG bit in the
system control register (SYSCR) determines
whether the interrupt is recognized at 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 mode
operating mode according to the table
