Setting the value of timer peripheral while running

I see. I do not have any other suggestions than using an offset that you handle in SW unfortunately, as there is simply no way to directly access the internal counter register.

I need to keep timestamps for my raw data. For this reason I have an external RTC module and the internal msec timer (TIMER1). The problem is that they come out of sync every once in a while. So I need to add subtract from the msec timer to keep RTC and Timer1 in sync.

I could use events for this but I need the microcontroller to be in sleep mode most of the time and wake up only in certain cases.

Thank you for your help

You cannot write to the internal counter in counter mode either (other than inputting the required amount of pulses to count to where you want to be).

What is it you want to acomplish? Can it be achieved in some other way (using an offset or something else)?

Any suggestions on how this can be done ( counter mode maybe)?

Hi,

You cannot set the internal counter to a specific value (except from clearing it to 0).
