Arm CoreLink SDK-101 System Design Kit Technical Overview : Real Time Clock

Real Time Clock

The Real Time Clock (RTC) is an AMBA® slave module that connects to the Advanced Peripheral Bus (APB).

The following figure shows the RTC block diagram.

The RTC can be used to provide a basic alarm function or long time base counter. This is achieved by generating an interrupt signal after counting for a programmed number of cycles of a real-time clock input. Counting in one second intervals requires a 1Hz clock input to the RTC.
