Using CLK pin for RTC

[kbell_hardware]

Hello,

I'm wondering if it is possible to not use the XTAL pins for your RTC clock input, but instead use the CLK1_P or CLK2_P pin. Using the IMX6Q

Thanks,

Kevin

Hi Kevin,

They are impossible to be acted as RTC function.

1. There is no path from CLK1_N/P and CLK2_N/P to RTC block.

2. CLK1_N/P and CLK2_N/P pins belong to VDD_HIGH_CAP power group not VDD_SNVS_IN.
