Event Counter
13.3 Event Counter Status/Control Register
EVCE — Event Counter Enable
EVIE — Event Counter Complete Interrupt Enable
EVOE — Event Counter Overflow Enable
EVIF — Event Counter Complete Interrupt Flag (read only)
EVOF — Event Counter Overflow Flag (read only)
RCCF — Reset Count Complete Interrupt Flag (write only)
ROIF — Reset Overflow Interrupt Flag (write only)
Bit 0 — Reserved
118
When a logic 1 is written to this bit, EVIF is cleared. Always reads as zero.
When a logic 1 is written to this bit, EVOF is cleared. Always reads as zero.
This bit is not used and always reads as zero.
1 = Event counter enabled
0 = Event counter disabled
1 = Event counter complete interrupt enabled
0 = Event counter complete interrupt disabled
1 = Event counter overflow interrupt enabled
0 = Event counter overflow interrupt disabled
1 = Flag set when gate delay time expires
0 = Flag cleared when logic 1 is written to ROIF
1 = Flag set when gate delay time expires
0 = Flag cleared when logic 1 is written to ROIF
