Overview
Real time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. RTCs are present in almost any electronic device which needs to keep accurate time. More general information here.
In IGEP Boards, MPU and PMIC contains each one a RTC clock:
- System clock: system clock is controlled by OMAP processors using its internal RTC peripheral
- Hardware clock: hardware clock is controlled by PMIC IC using its internal RTC peripheral
