9.10.9 Port P7 (P7.0 to P7.5) Input/Output With Schmitt Trigger

Figure 9-12 shows the port diagram. Table 9-57 summarizes the selection of the pin function.

(1) Setting P7SEL.x bit disables the output driver and the input Schmitt trigger.
(2) The pin direction is controlled by the USCI module.
(3) UCB2CLK function takes precedence over UCA2STE function. If the pin is required as UCB2CLK input or output, USCI_A2 is forced to 3-wire SPI mode if 4-wire SPI mode is selected.
(4) If the I2C functionality is selected, the output drives only the logical 0 to VSS level.
