15.4 Write Operation to Alarm time
*1) Non-existent alarm time can set in the alarm registers, but when it sets,
an alarm interrupt is disabled. To enable an alarm interrupt, existent
alarm time must be set in the alarm registers.
15.5 Second-digit Adjustment by ±30 seconds
*1) Set the ADJ bit to 1.
(The BSY bit is held at 1 for a maximum duration of 122.1s after the
ADJ bit is set to 1.)
15.6 Oscillation Start Judgment
*1) The XSTP bit is set to 1 upon power-on from 0V.
*2) It takes approximately 0.1 to 2 seconds to start oscillation. Provide an
exit from an oscillation start loop to prepare for oscillation failure.
Ensure stable oscillation by preventing the following:
1) Condensation on the crystal oscillator
2) Instantaneous disconnection of power
3) Generation of clock noises, etc, in the crystal
oscillator
4) Charge of voltage exceeding prescribed maxi-
mum ratings to the individual pins of the IC
