Section 7 I/O Ports
7.2.3
P1PCR controls the on/off status of the port 1 on-chip input pull-up MOSs.
7.2.4
Note: n = 7 to 0
7.2.5
Port 1 has an on-chip input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be specified as on or off on a bit-by-bit basis.
Table 7.2 summarizes the input pull-up MOS states.
Table 7.2

Legend:
Off: Input pull-up MOS is always off.
On/Off: On when the pin is in the input state, P1DDR = 0, and P1PCR = 1; otherwise off.
