Function
Connected to a plus power supply.
Connected to a 0 V power supply.
I/O pins of the system clock generating circuit. Connect a ceramic resonator
between pins X
IN
and X
OUT
. The feedback resistor is built-in between pins X
IN
and X
OUT
.
Each pin of port D has an independent 1-bit wide output function. The output
structure is P-channel open-drain.
1-bit I/O port. For input use, turn on the built-in pull-down transistor and set the
latch of the specified bit to “0.” In addition, key-on wakeup function using “H”
level sense becomes valid. The output structure is P-channel open-drain.
2-bit (E
0
, E
1
) output port. The output structure is P-channel open-drain.
3-bit input port. For input use (E
0
, E
1
), turn on the built-in pull-down transistor and
set the latch of the specified bit to “0.” In addition, key-on wakeup function using
“H” level sense becomes valid. Port E
2
has an input-only port and has a key-on
wakeup function using “H” level sense and pull-down transistor.
4-bit I/O port. For input use, set the latch of the specified bit to “0.” The output
structure is P-channel open-drain. Port G has a key-on wakeup function using
“H” level sense and pull-down transistor.
Carrier wave output pin for remote control. The output structure is CMOS circuit.
