Name and Functions
IRQ interrupt request 0 and 1: These are
input pins for edge-sensitive external
interrupts, with a selection of rising or
falling edge.
Wakeup interrupt request 0 to 7: These
are input pins for rising or falling- edge-
sensitive external interrupts.
Internal interrupt request 0: This is the
request pin for an edge-sensistive internal
interrupt, with a selection of rising or falling
edge.
Clock output: This is an output pin for
waveforms generated by the timer A output
circuit.
Timer C event input: This is an event
input pin for input to the timer C counter.
Timer C up/down select: This pin selects
up- or down-counting for the timer C
counter. The counter operates as a down-
counter when this pin is high, and as an up-
counter when low.
Timer F event input: This is an event input
pin for input to the timer F counter.
Timer FL output: This is an output pin for
waveforms generated by the timer FL
output compare function.
Timer FH output: This is an output pin for
waveforms generated by the timer FH
output compare function.
Timer G capture input: This is an input
pin for timer G input capture.
Port B: This is an 8-bit input port.
Port 4 (bits 2 to 0): This is a 3-bit I/O port.
Input or output can be designated for each
bit by means of port control register 4
(PCR4).
