• the pulse length
• the number of pulses, that is, the number of rising and falling flank pairs
In principle, more pulses may lead to reduced accuracy.
14.11.6.2 Memory storage
GUID-B49698FF-0AB2-4792-A7CB-5534313B6CA0 v2
The value of the accumulated time is retained in a non-volatile memory,
• at every falling edge of the input IN
• at every even 6 minutes, after a rising edge of the input IN
• after a manual addition of time
Consequently in case of a power failure, there is a risk of losing the difference in
time between actual time and last time stored in the non-volatile memory.
