7.2.2 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.
7.2.3 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
The input pull-up MOS is turned on when a P2PCR bit
is set to 1 in the input port state.
7.2.4 Pin Functions
P27, P26, P25, P24, P23, P22, P21, P20
The pin function is switched as shown below according to the state of the P2nDDR bit.
P2nDDR 0 1
Pin Function P27 to P20 input pins P27 to P20 output pins
