Data bus (upper): Bidirectional data bus.
Used for 8-bit data and upper byte of 16-bit
data.
Data bus (lower): Bidirectional data bus.
Used for lower byte of 16-bit data.
Wait: Requests insertion of a wait state in
the bus cycle when accessing external 3-
state address space.
the external address space is being read.
indicates that the external address space is
being written to. The upper half of the data
bus is valid.
indicates that the external address space is
being written to. The lower half of the data
bus is valid.
indicates that address output on the
address bus is valid.
Nonmaskable interrupt: Requests a
nonmaskable interrupt.
Interrupt request 0 to 7: These pins
request a maskable interrupt.
FRT counter clock input: Input pin for an
external clock signal for the free-running
counter (FRC).
output compare A output pin.
output compare B output pin.
FRT input capture A input: The input
capture A input pin.
