State machine logic in BCD-formatted RTCs

Keywords:real-time clock? binary-coded decimal?

When developing code to operate a real-time clock (RTC), it is often beneficial to understand how the clock core operating logic has been defined. This tutorial discusses the counter-chain structure used in Maxim's binary-coded decimal (BCD)-formatted RTCs. It provides some insight into the expected chip behaviour if improper or illegal contents are somehow installed.
