Is it possible to have both Arm cores running at different clock speed. Would seem logical, but can't find anything in docs other than using the independent WFI/WFE feature(s)

I have an application with requires M4 core running at high speed >180MHz for intermittant Ethernet/number intensive processing etc.
The M0 core for PWM/ low speed timing functions which could run of a 12MHz clock.

Want to keep the power consumption down.
