To USART1
NOTE: UART mode:
The UART clock can only be an input. If UART mode and UART function are selected, the P5.3/UCLK1 direction
is always input.
SPI, slave mode: The clock applied to UCLK1 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 P5.3/UCLK1 (in slave mode).
