8.4.3
Port 3 pins also function as SCI I/O pins (TxD0, RxD0, SCK0, TxD1, RxD1, and SCK1) and
interrupt input pins (IRQ4, IRQ5). Port 3 pin functions are shown in table 8.7.

Pin Functions
Port 3 Pin Functions
The pin function is switched as shown below according to the combination of
bit C/A in the SCI1 SMR, bits CKE0 and CKE1 in SCR, and bit P35DDR.
Notes: 1. When P35ODR = 1, the pin becomes an NMOS open-drain output.
