(2) The pin direction is controlled by the USCI module.
(3) UCA0CLK function takes precedence over UCB0STE function. If the pin is required as UCA0CLK input or output, USCI A0/B0 is forced
to 3-wire SPI mode if 4-wire SPI mode is selected.
(4) In case the I²C functionality is selected the output drives only the logical 0 to V_SS level.
