Currently the M4 on the BCM943341WCD1 seems to be setup for 120Mhz.

What is the slowest speed that we can run the chip at, and are there any app notes on how to change the clock speed ?

I want to run wifi/ble in this configuration.

You can run as slow as you want. But you need to calculate all the PLL settings and update the platform_config.h

Use the STM clock calculation tool to generate the values

We haven't tested extensively at low frequencies but 48MHz should work

STM32 supports lower CPU clock speed.

I think modifying RCC_CFGR changes clock.

But some numbers calculated by 120MHz (defined as CPU_CLOCK_HZ).

So please change clock speed carefully.

For detail of RCC registers, please refer ST information.
