8.3.2 Port 2 Data Register (P2DR)
P2DR stores output data for port 2.
Bit Bit Name Initial Value R/W Description
7 P27DR 0 R/W
6 P26DR 0 R/W
5 P25DR 0 R/W
4 P24DR 0 R/W
3 P23DR 0 R/W
2 P22DR 0 R/W
1 P21DR 0 R/W
0 P20DR 0 R/W
If a port 2 read is performed while P2DDR bits are
set to 1, the P2DR values are read directly,
regardless of the actual pin states. If a port 2 read
is performed while P2DDR bits are cleared to 0,
the pin states are read.
8.3.3 Port 2 Pull-Up MOS Control Register (P2PCR)
P2PCR controls the port 2 on-chip input pull-up MOSs.
Bit Bit Name Initial Value R/W Description
7 P27PCR 0 R/W
6 P26PCR 0 R/W
5 P25PCR 0 R/W
4 P24PCR 0 R/W
3 P23PCR 0 R/W
2 P22PCR 0 R/W
1 P21PCR 0 R/W
0 P20PCR 0 R/W
In modes 2 and 3, the input pull-up MOS is turned
on when a P2PCR bit is set to 1 in the input port
state.
