KW45 32MHz crystal oscillator parameter matching settings

[Taiyi]

I found this description in this document <<KW45B41Z-EVKUM>> Page29, saying that the frequency can be adjusted, but I did not find a configurable register in the <<KW45RM>> manual, where can I adjust it?

HI, @Taiyi 

Thanks for creating case to us.

I checked what you mentioned, and also not found related method/ register about how to adjust.

I may need to check internally then feedback to you.

It will need sometime. Once have any updates, I will keep you posted.

Best regards,

Christine.

Hi, @Taiyi 

Please refer to our Reference Manual Page:1738 (Section: 53.3.4.1.7 XO Test Register (XO_TEST)
). It mentioned: 

9-4
CDAC

XO On-chip Load Capacitor Trim
00_0000b - 6pF
11_1111b - 11pF

We also have related realization in SDK, the interface is: 

RFMC_SetXtalTrim() in wireless/XCVR/nb2p4ghz/rfmc_ctrl.c

Hope above information can help you somehow.

Best regards,

Christine.
