Bit Description
TRGIEN Trigger Interrupt Request Enable
0 Trigger interrupt request disabled.
1 Trigger interrupt request enabled. A request is generated if the TRGI flag is set.
TRGI Trigger Interrupt Flag. This flag is set by hardware when the trigger output request is generated after a valid input
event is detected. It is cleared by software.
0 No trigger output request.
1 Trigger output request generated.
