Hello,
Is the pull-down resistance not necessary to the CLK_32K_OUT pin ?
When there is no CLK output, does it become Hi-Z and cause malfunction due to noise?
Thanks for your help.

Hi yuji_matsunami,
The PMIC can work without problems with the CLK if you do not want to use it, do not leave floating the XTAL_IN terminal tie this to GND, and the XTAL_OUT terminal you can leave floating.
Hope this helps you.

Dear Israel-san,
sorry, we use CLK_32K_OUT.
When the CLK_32K_OUT is stop, does it become Hi-Z and cause malfunction due to noise?
Is the pull-down/pull-up resistance not necessary to the CLK_32K_OUT pin ?

Hi yuji_matsunami,
In that case, the answer is not, it can work without problems, of course, you can use a resistor to reduce the noise but the PCA has a system itself to reduce this, take a look at the datasheet 7.732 kHz Crystal Oscillator Driver.

Dear Israel-san,
Thanks for your support.
