9.3.1
Port 3 is an 6-bit I/O port. Port 3 is a multi-purpose port for SCI I/O pins (TxD0, RxD0, SCK0,
TxD1, RxD1, SCK1), external interrupt input pins (
SDA0, SCL1, SDA1). All of the port 3 pin functions have the same operating mode. The
configuration for each of the port 3 pins is shown in figure. 9-2.
