Section 8 I/O Ports
8.1.5
PCR is an 8-bit readable/writable register that controls on/off of the port input pull-up MOS.
If a bit in PCR is set to 1 while the pin is in input state, the input pull-up MOS corresponding to
the bit in PCR is turned on. Table 8.3 shows the input pull-up MOS status.
The initial value of PCR is H'00.

The input pull-up MOS is always off.
If PCR is set to 1, the input pull-up MOS is on; if PCR is cleared to 0, the input pull-up
MOS is off.
