9.4.1
Port 3 is a 6-bit I/O port. Port 3 pins also function as SCI I/O pins (TxD0, RxD0, SCK0, TxD1, RxD1, and SCK1). Port 3
pin functions are the same in all operating modes.
Figure 9-3 shows the port 3 pin configuration.
9.4.2
Table 9-6 shows the port 3 register configuration.

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. Bits 7 and
6 are reserved. P3DDR cannot be read; if it is, an undefined value will be read.
Setting a P3DDR bit to 1 makes the corresponding port 3 pin an output pin, while clearing the bit to 0 makes the pin an
input pin.
