Tuning LFXO / RTC

[Andrej]

Hi,

is there a possibility to tune the external xtal (lfxo) or the rtc?

In other microcontrollers there is a possibility to trim, for exampe the rtc ignores one or more tick every 15seconds.

Best regards

Hi,

 

You can tune the crystal frequency by adjusting the external load capacitors, but there is no on-chip functionality to tune it further unfortunately.

 

Best regards,
