3.IF 32KHz RTC WORKING CRYSTAL WORKING.BUT HOW CONFIRM RTC SECTION OF PCH (INTERNAL PART) WORKING AND IN THIS CONDITION WHICH SIGNAL WE ARE CHECK?
We know cristal circuit is used for rtc section which provides 32.768khz free clock when ever got some supply .
Am I right .
It's pin no.1 provides the sine wave of 32khz and on pin no.2 u will get the same output of 32khz but amplified and wave with little high amplitude . It indecates that cristal and rtc section working in good manner .
sus_clk is also the output of rtc section but having fullswing square wave of same 32khz . Once u got sus_clk it is sure ur rtc section working perfectly .
