The pin direction is controlled by the USCI module.
(4)
UCA0CLK function takes precedence over UCB0STE function. If the pin is required as UCA0CLK input or output, USCI_B0 is forced to
3-wire SPI mode if 4-wire SPI mode is selected.
3-wire SPI mode if 4-wire SPI mode is selected.
(5)
Setting the ADC10AE0.y bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals.
