IWRL6432: Where is PMIC_CLKOUT control supported in the SDK?

Hi,

We are looking into your query. Please allow us a couple of days to respond.

Regards,

Hello.

Are you looking to configure the PMIC_CLKOUT in any way or just read the output of the PMIC_CLKOUT?

Sincerely,

Santosh

We want to drive a clock signal out of the radar chip to synchronize the PMIC.

Understood.  You can pinmux the PMIC_CLKOUT out the PMIC_CLKOUT pin H11, as per the data sheet.  That should route the signal you want for any synchronization purposes.

Sincerely,

Santosh

Ok, but can you be more specific with a section in the TRM on which registers to set for pin muxing, also which registers to set for frequency control ot the output?  We could not find any details.

Hello Thomas.

Apologies in the delay in response due to the holidays.  Let me look into this and get a response to you by next week.

Sincerely,

Santosh

Hi Tom,

Can you look at the DCDC_CTRL_REG1 register? It looks like bit 16 enables the output. I found it in the TRM for reference.

Best,

Nate

Thank you Nathan.  Where does one find out how to set the PMIC_CLKOUT frequency?

And are there drivers in the MMWAVE_L_SDK for such calls?
