Nonmaskable interrupt: Nonmaskable interrupt request
signal. The rising or falling edge can be selected for
signal detection.
Interrupt request 0–7: Maskable interrupt request
signals. Level input or edge-triggered input can be
selected.
Slave interrupt request output: Indicates occurrence of
an interrupt while the bus is released.
Address bus: Outputs addresses.
Data bus: 16-bit bidirectional data bus that is
multiplexed with the lower 16 bits of the address bus.
Upper data bus parity: Parity data for D15–D8.
Lower data bus parity: Parity data for D7–D0.
Wait: Requests the insertion of wait states (T
the bus cycle when the external address space is
accessed.
