There are two sampling trigger sources available which can be selected through the TRIGSRC bit in the CTL1 register; one is a software trigger and the other is an event trigger.
When the software trigger is selected as the source, the application software can set the Start Conversion (SC) bit in the CTL1 register to initiate the sample phase. When the event trigger is selected as the source, a rising edge on the selected event from the event manager initiates the sample phase. An event is always edge triggered.
There are two sampling modes available, AUTO and MANUAL, which are selected through the SAMPMODE bit in the CTL1 register.
