Subject: RTC alarm questions

RTC alarm questions

From: Uwe Freese <>
Date: Mon, 30 Dec 2002 12:36:23 +0100


The RTC (Recorder) has an alarm function. Is the output pin for this
alarm connected to the cpu or not?

Is it connected anywhere else?

Is the alarm used for some timed functions at the moment?

My idea was: If the alarm pin is not connected anywhere, I'd like to
make a modification that can turn the AJB on. I would add a
transistsor and connect it somehow to the alarm output pin and the
"ON" button so that an alarm has the same effect as pressing "ON".

Bye, Uwe.
