Name and Function
Wait: Requests insertion of a wait state in the bus
cycle when accessing external 3-state address
space.
external address space is being read.
the external address space is being written to. The
upper half of the data bus is valid.
external address space is being written to. The
lower half of the data bus is valid.
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).
compare A output pin.
compare B output pin.
FRT input capture A input: The input capture A
input pin.
FRT input capture B input: The input capture B
input pin.
FRT input capture C input: The input capture C
input pin.
FRT input capture D input: The input capture D
input pin.
