These are I/O pins of internal clock generating circuit for the main
clock. To control generating frequency, an external ceramic resona-
tor is connected between X
IN
and X
OUT
pins. If an external clock is
used, the clock oscillation source should be connected to the X
IN
pin, and the X
OUT
pin should be left open. Feedback resistor is con-
nected between X
IN
and X
OUT
.
8-bit I/O port. The output structure is CMOS output.
When this port is selected for input, a pull-up transistor can be con-
nected in units of 1 bit, and a key-on wake-up function is provided.
