Note The INTP7 pin and RXDA0 pin are alternate-function pins. When using the pin as the RXDA0 pin, disable edge detection for the alternate-function INTP7 pin (clear the
INTF3.INTF31 bit and INTR3.INTR31 bit to 0). When using the pin as the INTP7 pin, stop the UARTA0 reception operation (clear the UA0CTL0.UA0RXE bit to 0).
Caution When using one of the P10 and P11 pins as an I/O port and the other as a D/A output pin (ANO0, ANO1), do so in an application where the port I/O level does not
change during D/A output.
