8.2.2 Port 2 Data Register (P2DR)
P2DR stores output data for the port 2 pins.
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
P2DR stores output data for the port 2 pins that are
used as the general output port.
If a port 2 read is performed while the P2DDR bits
are set to 1, the P2DR values are read. If a port 2
read is performed while the P2DDR bits are
cleared to 0, the pin states are read.
8.2.3 Port 2 Pull-Up MOS Control Register (P2PCR)
P2PCR controls the port 2 built-in 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
When the pins are in input state, the corresponding
input pull-up MOS is turned on when a P2PCR bit
is set to 1.
