Note: Whenever more than one event occurs si-
multaneously, the action taken will be the result of
ANDing the event bits xxE1-xxE0.
Bit 7:6 = C0E[0:1]: COMP0 event bits.

Bit 1 = CEV: On-Chip event on CMP0R.
This bit is set and cleared by software.
0: No action
1: A successful compare on CMP0R activates the
on-chip event signal (a single pulse is generat-
ed)
Bit 0 = OP: TxOUTA preset value.
This bit is set and cleared by software and by hard-
ware. The value of this bit is the preset value of the
TxOUTA pin. Reading this bit returns the current
state of the TxOUTA pin (useful when it is selected
in toggle mode).
