7.3.2 Port 3 Data Register (P3DR)

P3DR stores output data of port 3.

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

0 P30DR 0 R/W

If a port 3 read is performed while P3DDR bits are set

to 1, the P3DR values are read directly, regardless of

the actual pin states. If a port 3 read is performed while

P3DDR bits are cleared to 0, the pin states are read.

7.3.3 Port 3 Pull-Up MOS Control Register (P3PCR)

P3PCR controls the port 3 on-chip input pull-up MOSs on a bit-by-bit basis.

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

0 P30PCR 0 R/W

The input pull-up MOS is turned on when a P3PCR bit

is set to 1 in the input port state.

The input pull-up MOS function cannot be used when

the host interface is enabled.
