RX8804CE
1) Time stamp SEC ~ YEAR
In case of trigger input detection from EVIN terminal, Clock and calendar data are recorded in Time
stamp SEC ~ YEAR.
2) TSVLF, TSVDET bit (Time stamp VLF, Time stamp VDET)
In case of trigger input detection from EVIN terminal, VLF bit is recorded to TSVLF, VDET bit to TSVDET.
3) ECP bit (Event capture Enable)
ECP enables Time Stamp function.

Time stamp is disabled
Time stamp is enabled
Time stamp data are overwritten by latest time stamp data
EVIN pin detects active Low level
EVIN pin detects active High level
Pull-up resistor is disabled
Pull-up resistor is enabled
After time stamp, ECP bit is cleared to 0 automatically and Time stamp is not
executed, till ECP is set to 1 again
Repeated Time stamp is enabled
After a Time stamp execution, ECP is not cleared to 0
Time stamp is executed in every event detection and overwrites to Timestamp
register
/INT Low output is cleared to Hi-Z
The value of EF bit remains even EF = 0 or EF = 1
To keep the EF bit value, please write 1 to EF bit
There is no EVIN detection history
There is EVIN detection history
