STD Frequency divider 1/3600
No Profile
Description
**Frequency divider 1/3600**
Will be used together with DS1307 RTC module to generate hourly pulse (from SQW/OUT configured to 1 Hz tick).
DS1307 should run on VBAT only, divider module will run on 3.3V.
Falling edge of pulse will be used to wake-up Atmel MCU from deep-sleep...
