The easiest way to build a RTC:
Use the timers T0 or T1 and count seconds, minutes and so on direct inside Bytes of the internal SRAM. Advantages: No awkward data protocol, conversion and synchronisation needed. Easy access, since always inside the RAM. Higher crystal (12MHz instead 32kHz) provide typically higher accuracy (less temperature sensitive). The only disadvantage: Higher current consumtion if it must be battery powered. Peter |
