Timer2 maximum clock frequency on nucleo f401
Hi,
reading the reference manual of stm32f401 processor (DM00096844), I would expect the timer 2 clock frequency to be the double of APB1 frequency when TIMPRE is 0, as I see in my case.
I measure something as 42 MHz, meaning that I am generating a pwm from tim2 oc1 with a 50 % duty cycle and measuring the period of this pwm. I see a period that is double of what I expected.
Questions:
1) Is it correct to expect 84 MHz, or the timer clock maximum frequency is limited to the set APB1 frequency?
2) Is there any other prescaler I am missing, for example in the OCx output?
Regards.
