Pull-Up MOS Control Register (PnPCR) (n = D to F, H, and I)

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 8.4 shows the input pull-up MOS status.
The initial value of PCR is H'00.
