Issue with disabling Timer0 Interrupt

Other Parts Discussed in Thread: CONTROLSUITE

Hello,

I want to disable Timer's 0 interrupt while performing a small amount of code, i.e.

CpuTimer1Regs.TCR.bit.TIE = 0
Some Code
CpuTimer1Regs.TCR.bit.TIE = 1

However, if the timer wraps around during the execution of some code, the ISR won't be called after re-enabling the interrupt.

Disabling the the PIE doesn't work either, i.e.

PieCtrlRegs.PIEIER1.bit.INTx7=0
Some Code
PieCtrlRegs.PIEIER1.bit.INTx7=1

because SEQ1INT will be called if the interrupt occurs during the execution of some code.


What am I missing?

Stephen

    Hi Stephen,

    CpuTimer1Regs.TCR.bit.TIE = 0
    Some Code
    CpuTimer1Regs.TCR.bit.TIE = 1

    The above code should do the trick. I don't know why it isn't working for you. I would like you to check the same with cpu_timer example code available in controlSuite.
    Regards,

    Hello Stephen,

    Shouldn't it be:

    CpuTimer0Regs.TCR.bit.TIE = 0 // Disable timer 0

    Some code

    CpuTimer0Regs.TCR.bit.TIE = 1 // Enable timer 0

    if you want to stop timer 0.

    Best regards,
