I design a board on IMX6DUAL,but I am not sure of RTC.How to use RTC?
Is it mean that RTC embeded in imx6, I can only supply a 32.768khz external oscillator or a crystal or a crystal using the internal oscillator amplifier ? where is the power-pin to supply for RTC when IMX6 power off? Is it VDD_SVNS_IN?
If I not like to use the RTC of IMX6,can I use a RTC IC external?like PCF8563,with its 32.768KHZ and 3.3v battery?
