NOTES:
1. X: Don’t care.
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_B0 will be
forced to 3-wire SPI mode even if 4-wire SPI mode is selected.
4. In case the I2C functionality is selected the output drives only the logical 0 to VSS level.
5. UCB0CLK function takes precedence over UCA0STE function. If the pin is required as UCB0CLK input or output USCI_A0 will be
forced to 3-wire SPI mode even if 4-wire SPI mode is selected.
