(1) X: Don’t care
(2) The pin direction is controlled by the USCI module.
(3) UCA1CLK function takes precedence over UCB1STE function. If the pin is required as UCA1CLK input or output USCI A1/B1 will be
forced to 3-wire SPI mode if 4-wire SPI mode is selected.
(4) The pin direction is controlled by the USCI module.
(5) In case the I²C functionality is selected the output drives only the logical 0 to V_SS level.
