Port P0 (P03 to P00)
Port P0 is a 4-bit input/output port that can be set to input or output for each bit individually, and it is also
used as the high-frequency oscillation connection pin and the low-frequency oscillation connection pin.
Port P0 contains a programmable pull-up resistor on the VDD side. This pull-up resistor can be used when
the port is used in the input mode.
