Currently, in ISR, I read time and

Gives a warning! alarm_is_ringing is a bit variable!
if ALRMRPT then
What is ALRMRPT, and where is it set with which value???
onboard_led = !onboard_led
end if
end if
PIR3_RTCCIF = false -- clear flag
end procedure
You better had attached a (subset of) your complete program.
