Bit 4 – ISREL Event Uses Relative Timing

Value	Description
`0`	Event start time is an absolute time.
`1`	Event start time is relative to the wall clock time when the START bit is written.

Bit 3 – REP Event Repeats Periodically

Value	Description
`0`	Event occurs once.
`1`	Event repeats periodically. The period equals pulse width plus idle time.

Bit 2 – AH Event Output is Active High

Note: This bit has no effect if pulse width = 0 (toggle mode).

Value	Description
`0`	Event is active low - signal will be driven low at event start for the duration of the pulse width, then will transition to and remain low for the idle time.
`1`	Event is active high - signal will be driven high at event start for the duration of the pulse width, then will transition to and remain low for the idle time.

Bit 1 – STOP Stop Event

Note: Only events with REPEAT=1 need to be stopped.

Value	Description
`0`	No effect
`1`	Stop repeating pulses at the end of the next idle time. The output will remain at the idle value and event done status bit will be set.

Bit 0 – START Start Event

Value	Description
`0`	No effect
`1`	Start the event configured in this register.
