    DMA interrupt at IRDV value on TC375

    Dear all,

    I tried to set an interrupt when CHSR.TCOUNT equals the ADICR.IRDV value. I can verify with the debugger the setting in ADICR.IRDV
    to something I like to see and obviously higher than zero. However, the DMA interrupt is always raised when TCOUNT = 0 and not the value I set in ADICR.IRDV. It ooks like
    the ADICR.IRDV setting is ignored. Any idea how I can debug this case?

    Best Regards
    Markus

    Are you sure your ADICR.INTCT value is correctly set? This defines the behavior when an interrupt will be triggered.
