Hello Group,
While reading some requirement specification I came across a term called "sleep clock". I know it it related to a power saving mechanism. I but I am not sure how it works exactly. Is it some kind of gating mechanism where the processor controlling the system power distribution, gives out a signal to suggest to other peripherals on the PCB to go in power down mode?

In most cases with which I am familiar, a "sleep clock" is a clock source that is much slower than the main system clock and that can be used, in company with a timer or RTC peripheral, to periodically bring the CPU out of a low power mode. It is often a 32.768 KHz watch crystal.
