Gr8 qustion brother how to check rtc wether it is working or not .
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 .
