M41T81, Serial access real-time clock

The M41T81 is a low-power serial RTC with a built-in 32.768 kHz oscillator (external crystal controlled).

Eight bytes of the SRAM are used for the clock/calendar function and are configured in binary-coded decimal (BCD) format.

An additional 12 bytes of SRAM provide status/control of alarm, watchdog
