0: Input

1: Output

NOTE: UART mode:

The UART clock can only be an input. If UART mode and UART function are selected, the P3.3/UCLK0 is always

an input.

SPI, slave mode:

The clock applied to UCLK0 is used to shift data in and out.

SPI, master mode:

The clock to shift data in and out is supplied to connected devices on pin P3.3/UCLK0 (in slave mode).
