Input IRQ interrupt request 0,
1, 3, and 4: These are
input pins for edge-
sensitive external
interrupts, with a selection
of rising or falling edge

Asynchronous event
counter event signal:
This is an interrupt input
pin for enabling
asynchronous event
input.
On the H8/38124 Group,
this must be fixed at V
CC
or GND because the
oscillator is selected by
the input level during
resets. Refer to section 4,
Clock Pulse Generators,
for information on the
selection method.
