Name and Functions
These pins connect to a
crystal or ceramic
oscillator, or can be used
to input an external clock.
See section 4, Clock
Pulse Generators, for a
typical connection
diagram.
These pins connect to a
32.768-kHz or 38.4-kHz *
crystal oscillator.
See section 4, Clock
Pulse Generators, for a
typical connection
diagram.
Reset: When this pin is
driven low, the chip is
reset
Test pin: This pin is
reserved and cannot be
used. It should be
connected to V
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
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.
