Signal | Description of Event | Register Bitfields Compared |
---|---|---|
CMPA_eq | Time-base counter equal to the active counter-compare A value | TBCNT = CMPA |
CMPB_eq | Time-base counter equal to the active counter-compare B value | TBCNT = CMPB |
PRD_eq | Time-base counter equal to the active period. Used to load active counter-compare A and B registers from the shadow register | TBCNT = TBPRD |
CNT_zero | Time-base counter equal to zero. Used to load active counter-compare A and B registers from the shadow register | TBCNT = 0000h |
