Bit Field Value Description
31-5 Reserved 0 Reads return 0. Writes have no effect.
4 EV_EDG_BOTH EV Group Trigger Edge Polarity Select. This bit configures the event group to be triggered on both
rising and falling edge detected on the selected trigger source.
Any operation mode read/write:
0 The conversion is triggered only upon detecting an edge defined by the EV_EDG_SEL bit.
1 The conversion is triggered upon detecting either a rising or falling edge.
3 EV_EDG_SEL Event Group Trigger Edge Polarity Select. This bit determines the polarity of the transition on the
selected source that triggers the Event Group conversion.
Any operation mode read/write:
0 A high-to-low transition on the selected source will trigger the Event Group conversion.
1 A low-to-high transition on the selected source will trigger the Event Group conversion.
2-0 EV_SRC Event Group Trigger Source.
Any operation mode read/write:
0-7h The ADC module allows a trigger source to be selected for the Event Group from up to eight
options. These options are device-specific and the device specification must be referred to identify
the actual trigger sources.
