clock setting sequence using the High Frequency mode

Genius 5960 points
Other Parts Discussed in Thread: MSP430F435


I am using the MSP430F435.

The LFXT1 is used in high-frequency mode,
I am going to MCLK / ACLK both use the LFXT1.
(SMCLK stop planned)

MSP430F435 is but I think it works in the DCO by default,
Is there a recommended setting sequence in order to operate in the high-frequency mode?

Best Regards,


  • The normal answer for this kind of question would be "use driverlib", but that code supports only the low-frequency mode.

    Try copying the code of the CS_XT1Start() function, but change it to set the XTS bit, and to initialize HFFREQ and DIVA.
