Events

The ADC can generate the following events:

Table 1. Event Generators in ADC
Generator Name		Description	Event Type	Generating Clock Domain	Length of Event
Peripheral	Event	Description	Event Type	Generating Clock Domain	Length of Event
ADCn	RESRDY	Result ready	Pulse	CLK_PER	One clock period

The conditions for generating an event are identical to those that will raise the corresponding flag in the Interrupt Flags (ADCn.INTFLAGS) register.

The ADC has one event user for detecting and acting upon input events. The table below describes the event user and the associated functionality.

Table 2. Event Users and Available Event Actions in ADC
User Name		Description	Input Detection	Async/Sync
Peripheral	Input	Description	Input Detection	Async/Sync
ADCn	START	ADC start conversion	Edge	Async

The ADC can be configured to start a conversion on the rising edge of an event signal by writing a ‘1’ to the STARTEI bit field in the Event Control (ADCn.EVCTRL) register. Refer to the Event System (EVSYS) section for more details regarding event types and Event System configuration.

When an input event trigger occurs, the positive edge will be detected, the Start Conversion (STCONV) bit in the Command (ADCn.COMMAND) register will be set, and the conversion will start. When the conversion is completed, the Result Ready (RESRDY) flag in the Interrupt Flags (ADCn.INTFLAGS) register is set and the STCONV bit in ADCn.COMMAND is cleared.
