ST67W611M1: measure frequency of external 32.768 kHz crystal oscillator circuit

[PKR]

Dear all,

is it possible to measure the frequency of the 32,768kHz oscillator (external crystal used) at a buffered pin similar to the MOC pin of the STM32 to tune the frequency by the external capacitors? It would be difficult to do this at pin XTAL32k_IN/OUT without influencing the oscillator frequency.

Best regards,

Peter

There is a divided output  - check you processor data sheet

I could't finde any hint in the ST67W611M1 module / QCC743 SoC datasheets. Could you provide details?

Hi @PKR 

The 32 kHz clock signal cannot be routed on a GPIO to perform such measurement.
