2.3.55 PS2 / RXD1 — Port S I/O Pin 2

PS2 is a general purpose input or output pin. It can be configured as the receive pin RXD of Serial

Communication Interface 1 (SCI1).

2.3.56 PS1 / TXD0 — Port S I/O Pin 1

PS1 is a general purpose input or output pin. It can be configured as the transmit pin TXD of Serial

Communication Interface 0 (SCI0).

2.3.57 PS0 / RXD0 — Port S I/O Pin 0

PS0 is a general purpose input or output pin. It can be configured as the receive pin RXD of Serial

Communication Interface 0 (SCI0).

2.3.58 PT[7:0] / IOC[7:0] — Port T I/O Pins [7:0]

PT7-PT0 are general purpose input or output pins. They can be configured as input capture or output

compare pins IOC7-IOC0 of the Enhanced Capture Timer (ECT).
