Hi,

How i can set APLL_CLK parameters directly through registers using esp-idf ?

APLL_CLK parameters:
* SDM0
* SDM1
* SDM2
* ODIV

Enable and disable APLL_CLK too if possible.

Without using this function "rtc_clk_apll_enable( 1, sdm0, sdm1, sdm2, odiv);".

Thank's.

Why?

I know this function.

Just for me to learn and maybe get more expert in bare metal programming.

Thank's.

If you look at the source code of the function I linked you will see how it is done.
