CPU Timer1 disable interrupt

Yehuda Bitton

Hi,

I am using F28377D, I wrote a drive which can start, stop and enable interrupt for CPUTimer1.

But when i try to disable interrupt of timer1 (INT13) it is not being disabled.

I do:

IER &= (~M_INT13);

In the watch window i can see that the relevant bit in IER register is being cleared, but afterwards it is being set again.

Any clue? maybe example code for disabling CpuTimer1 or 2?

Thanks.

    Hi,

    Instead try this:

    CpuTimer1Regs.TCR.bit.TIE = 0;				//Disable CPU Timer Interrupt

    Regards,

    IER is part of the context save/restore.  So if you are changing the value (to 0) within an interrupt, it will get restored to the previous value (1) when the interrupt exits.
