Table 8.7 shows the port 3 register configuration.
Table 8.7
Note:
Port 3 Data Direction Register (P3DDR)
P3DDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port 3. P3DDR cannot be read; if it is, an undefined value will be returned.
P3DDR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.

Read/Write
Modes 1, 2, and 3 (EXPE = 1)
The input/output direction specified by P3DDR is ignored, and pins automatically function as
data I/O pins.
After a reset, and in hardware standby mode or software standby mode, the data I/O pins go to
the high-impedance state.
Modes 2 and 3 (EXPE = 0)
The corresponding port 3 pins are output ports when P3DDR bits are set to 1, and input ports
when cleared to 0.
