Is there any hardware bug with NRF51822's TIMER2 and RTC1?

[Mathias Costa]

Hello there,

I am working in my master degree project with nordic NRF51822 microcontroller, but I faced two problems. I don't know if is a SD problem or hardware problem.

Fist, the TIMER2: cannot set the prescaler with different value from 9 and have control of the compare value (CC). The peripheral does not obey me. The only way to coherent set the frequency is working with Prescaler = 9, then the CC values work.

Second, the RTC1 does not trigger CC interrupt/event, then I can't handle multiple Counters value. I just can work with Tick and Overflow event/interrupt.

Is there some bug with the chip?

Hello,

Have you tested the TIMER and the RTC examples from the SDK? I suspect that the reason it is not working is that these are being used by something else. Do you e.g. use the app_timer module?

What SDK version are you using?

How does the TIMER2 behave different when you use prescaler = 9 and != 9?
