(1)

X = Don't care

(2)

The pin direction is controlled by the USCI module.

(3)

UCB3CLK function takes precedence over UCA3STE function. If the pin is required as UCB3CLK input or output, USCI A3 is forced to

3-wire SPI mode if 4-wire SPI mode is selected.

(4)

UCA3CLK function takes precedence over UCB3STE function. If the pin is required as UCA3CLK input or output, USCI_B3 is forced to

3-wire SPI mode if 4-wire SPI mode is selected.

(5)

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.
