What is considered a "GPIO Pin Event"?

[aberger]

I am reviewing the Reference Manual for the MCX A153 and trying to understand ADC triggering. Four of the available trigger sources are "GPIOn Pin Event Trig 0". What constitutes a GPIO Pin Event? How are they configured?

Hello @aberger 

ADC trigger sources select from register:

"ADC Trigger input connections (ADC0_TRIG0 - ADC0_TRIG3)".

About detail configuration, recommend refer to SDK demo "frdmmcxa153_1_lpadc_trigger_exception".

You can contact us if still have any issue.
