Notes 1. The INTP7 and RXD0 pins are alternate-function pins. When using the pin as the RXD0 pin, disable edge detection of the alternate-function INTP7 pin (clear
the INTF3.INTF31 and INTR3.INTR31 bits to 0). When using the pin as the INTP7 pin, stop the UART0 receive operation (clear the ASIM0.RXE0 bit to 0).
2. The ASCK0 and ADTRG pins are alternate-function pins. When using the pin as the ASCK0 pin, disable the trigger input of the alternate-function ADTRG pin
(clear the ADS.TRG bit to 0 or set the ADS.ADTMD bit to 1). When using the pin as the ADTRG pin, do not set the UART0 operation clock to external input
(set the CKSR0.TPS03 to CKSR0.TPS00 bits to other than 1011).
