Hello,
I am working on an audio amplifier automatic maximum power controller using an XMC4700 relax dev board and the DtoA driving a VCA.
I want to use a timer to measure soft clipping time, timer work in two ways:
1) High-level port pin state exceeds an alarm amount between 50uS and 100mS, then an interrupt.
2) The entire high-level state time is captured, so rising edge to falling edge, then an interrupt.
Which pins, timers do I use? do i need to use two port pins and two timers?
Thanks
Gary
