8.3.2 Port 3 Data Register (P3DR)
P3DR stores output data for the port 3 pins.
Bit Bit Name Initial Value R/W Description
7 P37DR 0 R/W
6 P36DR 0 R/W
5 P35DR 0 R/W
4 P34DR 0 R/W
3 P33DR 0 R/W
2 P32DR 0 R/W
1 P31DR 0 R/W
P3DR stores output data for the port 3 pins that are
used as the general output port.
If a port 3 read is performed while the P3DDR bits are
set to 1, the P3DR values are read. When the P3DDR
bits are cleared to 0, 1 is read.
0 P30DR 0 R/W
8.3.3 Port 3 Pull-Up MOS Control Register (P3PCR)
P3PCR controls the port 3 built-in input pull-up MOSs.
Bit Bit Name Initial Value R/W Description
7 P37PCR 0 R/W
6 P36PCR 0 R/W
5 P35PCR 0 R/W
4 P34PCR 0 R/W
3 P33PCR 0 R/W
2 P32PCR 0 R/W
1 P31PCR 0 R/W
When the pins are in input state, the corresponding
input pull-up MOS is turned on when a P3PCR bit is set
to 1.
0 P30PCR 0 R/W
