Select the port A GPIO signal (GPIO0 - GPIO31) that will be used as the XINT1 or XINT2
interrupt source. In addition, you can configure the interrupt in the XINT1CR or XINT2CR
registers described in
To use XINT2 as ADC start of conversion, enable it in the ADCTRL2 register. The ADCSOC
signal is always rising edge sensitive.
00000 Select the GPIO0 pin as the XINTn interrupt source (default)
00001 Select the GPIO1 pin as the XINTn interrupt source
. . . . . .
11110 Select the GPIO30 pin as the XINTn interrupt source
11111 Select the GPIO31 pin as the XINTn interrupt source
