.
Ground level input pin for A-D converter. Apply the same voltage as Vss. (This
pin is for 44P6N-A package only.)
Reference voltage input pin for A-D converter. (When the A-D converter is not
used, connect it to V
CC
.)
Reset input pin active “L”.
These are I/O pins for the internal clock generating circuit of the main clock. To
control the generating frequency, an external ceramic is connected between
the X
IN
and X
OUT
pins. If an external clock is used, the clock source should be
connected to the X
IN
pin, and the X
OUT
pin should be left open. The feedback
resistor is connected between X
IN
and X
OUT
.
8-bit I/O port. The output structure is CMOS output.
When this port is selected for input, pull-up transistors can be connected in
units of 1 bit, and a key-on wake-up function is provided.
8-bit I/O port. The output structure is CMOS output.
When this port is selected for input, pull-up transistors can be connected in
units of 4 bits. P1
