External (GPIO Pins)
This trigger is connected to the GPIO interrupt for the
corresponding GPIO (see “ADC Trigger Source” on page 616).
Note:
GPIOs that have AINx signals as alternate
functions can be used to trigger the ADC. However,
the pin cannot be used as both a GPIO and an
analog input.
0x5
Timer
In addition, the trigger must be enabled with the TnOTE bit
in the GPTMCTL register (page 697).
