How do I disable XTAL32 pin in K64 ?

[nitinharish]

Our circuit has an issue and for the time being, I want to disable XTAL32 output of K64 and RTC_CLKOUT pin output on PTE26.

Is their any way I can accomplish this without disabling RTC module in the BSP ?

I have tried setting SIM_SOPT2[RTCCLKOUTSEL] = 1 and RTC_CR[CLK0] = 0 which means 32.7KHz will be selected as an output on RTC_CLKOUT pin but then I disable any output on RTC_CLKOUT by doing RTC_CR[CLK0] = 0

mjbcswitzerland, I am back. Do you bless my approach above ?

Thanks and Regards

Hi, Nitin

You can find block diagram as below. So you can set SIM_SOPT2[RTCCLKOUTSEL] = 1 and RTC_CR[CLK0] = 1.

I did follow from the exact same source.

Thanks for the confirmation.
