7.1.4 Pull-Up MOS Control Register (PnPCR) (n = 1 to 3, 9, B to D, F, H, and J)
Pull-Up MOS Control Register (KMPCR) (Port 6)
PCR is a 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 the input state, the input pull-up MOS corresponding
to the bit in PCR is turned on. Table 7.3 shows the input pull-up MOS state. The upper two bits in
P9PCR and the upper two bits in PHPCR are reserved.
PBPCR to PDPCR, PFPCR, and PHPCR are valid only when PORTS in PTCNT2 is 1.
Bit Bit Name Initial Value R/W Description
7 Pn7PCR 0 R/W
6 Pn6PCR 0 R/W
5 Pn5PCR 0 R/W
4 Pn4PCR 0 R/W
3 Pn3PCR 0 R/W
2 Pn2PCR 0 R/W
1 Pn1PCR 0 R/W
For pins in the input state corresponding to bits in
this register that have been set to 1, the input pull-
up MOSs are turned on.
