(1) N/A: Not available or not applicable
(2) UC0CLK function takes precedence over UC0STE function. If the pin is required as UC1CLK input or output, USCI0 is forced to 3-wire
SPI mode if 4-wire SPI mode is selected.
(3) X: Don't care
(4) Default after reset (PUC/POR)
(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.
