enabled when UART1 enables the serial clock output.

P45

General I/O port. This function is enabled when UART1

disables the serial data output.

SOT1

Serial data output pin for UART1. This function is enabled when

UART1 enables the serial data output.

P46

General I/O port. This function is enabled when the Extended

I/O serial interface disables the serial data output.

SOT2

Serial data output pin for the Extended I/O serial interface. This

function is enabled when the Extended I/O serial interface

enables the serial data output.

P47

General I/O port. This function is enabled when the Extended

I/O serial interface disables the clock output.

SCK2

Serial clock pulse I/O pin for the Extended I/O serial interface .

This function is enabled when the Extended I/O serial interface

enables the Serial clock output.
