PCF85063A RTC

Hi,

I'm unable to read or write the values to PCF85063A AT, when I try to read I can see only zeros or the value of date will be more than 99(year).

Hi Divith,

please share your schematic with part values and voltage levels.

Please provide a scope from CLKOUT pin. Please note, that the CLKOUT pin is enabled if the CLKOE is high if you are using the ATL version. And the COF[2:0] bits must be other, than 111.
