Hello
Question: On what clock/clock-speed does the system tick timer run, when configured to use the external clock instead of the CPU clock?
I've seen a couple of threads discussing the system tick timer using the processor clock (CPU clock) as a clock source. I've also had a look a the nrf_systick and nrfx_systick from the SDK, however there is also allways the CPU clock used.
I'm aware that the systeem tick timer is a feature of the ARM cortex and configuring it to use the CPU clock makes it run at 64MHz, but still the question about the external clock remains.
