Section 7 I/O Ports
7.3.3
P2PCR controls the port 2 on-chip input pull-up MOSs.
7.3.4
Note: n = 7 to 0
7.3.5
Port 2 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 7.3 summarizes the input pull-up MOS states.
