PSoC 4 MCU

New Contributor II

Hello there,

Do you know if is possible to change the sysclock frequency for a PSOC 4 dynamically?

I need to run most of the time the PSoC @ 1.5 MHz, but occasionally I need to run at 48 MHz.

CySysClkWriteSysclkDiv(); should do the job... but it doesn't seems to work. 

Do you have any suggestions?

 

Thank you!

Have a look at the response to this post I put up last year - it makes mention of changing the IMO frequency dynamically.  I never ended up trying it, as I was able to solve my issue using a different approach
