Connected to plus power supply.
Connected to 0V power supply.
Each pin of port D has an independent 1-bit wide output function. Each port is used for key-
scan output. The output structure is N-channel open-drain.
1-bit I/O port. The output structure is N-channel open-drain. This port has a pull-up function
and a key-on wakeup function only at input.
4-bit I/O port. The output structure is N-channel open-drain. Each port has a pull-up function
at input/output. Also, each port has a key-on wake-up function at input.
Carrier wave output port for remote control transmitters.
The output structure is CMOS output.
Reset pulse is input to this pin. This pin has a pull-up resistor and a capacitor.
I/O pins of the system clock generating circuit.
XIN and XOUT can be connected to a ceramic resonator.
A feedback resistor is built-in between them.
Connected to VSS. Supply “L” (0V) certainly.
