How to measure NR52840 CPU clock

[jayaram]

Hi,

Can we route the CPU clock to any gpio pin to measure.?

Toggle a pin with a timer or PWM peripherial, measure the frequency on the pin.

Hi Turbo. How can we confirm it is 64MHz. I am just toggling a GPIO pin in a while loop and I am getting 8MHz pulses. How can I make sure it is 64MHz.
