I use RTC alarm to interrupt at specific seconds
I have problems that look like a 1s delay... Is interrupt set at the END of the second that match with alarm register ?
I'm not sure what I read in datasheet :
When the time counter is enabled, the SR[TAF] is set whenever the TAR[TAR] equals the TSR[TSR] and
the TSR[TSR] increments.
TAR = TSR and then interruption + TSR increments (not 1 second delay with alarm register)
or TAR = TSR and then TSR increments and then interruption ? (1 second delay after alarm register match)
Thank you in advance
PS : I'm using a K64
