14.8.3. Time stamp function triggered by EVIN pin input
Following registers control time stamp function triggered by EVIN pin input.
1) ETS bit (Enable Time Stamp)
This register controls time stamp (triggered by EVIN pin input) ON/OFF. Also, user can use chattering prevention function. User
should be aware that chattering prevention results in the worse resolution. (refer to ET1, ET0bit.)

2) EVF bit (Event Flag)
This register is be set to “1” when event occurs.

4) EHL bit (EVIN High/Low)
This register controls EVIN input voltage level.
Longer EVIN input than chattering prevention cycle is detected.
