18.5.2 Writing clock data
1. Using 1Hz interrupt
2. Resetting counter
correct data writing.
A carry during writing ruins correct data writing. The following procedure ensures the
counter. If data is written in the time between 1Hz interrupt and subsequent one second
count, it completes correctly.
counter reset. The time must be set within one second after the interrupt.
The 1Hz interrupt is generated being synchronized with counting up of the sec.
Write data after resetting the sec. counter.
The 1Hz-interrupt is generated one second after enabling the interrupt subsequent to
