Note The INTP7 pin and RXDA0 pin are alternate-function pins. When using the pin as the RXDA0 pin, disable
edge detection for the INTP7 alternate-function pin. (Clear the INTF3.INTF31 bit and the INTR3.INTR31
bit to 0.) When using the pin as the INTP7 pin, stop UARTA0 reception. (Clear the UA0CTL0.UA0RXE bit
to 0.)
