I'm using a RT685 and have a question about the CTIMER peripherals. Each match unit has its own external output that can be set, cleared or toggled. One CTimer's match unit can't seem to change the state of a different match unit.
For context, my design requires coordination of DMA and an output pin. I need to trigger DMA once a given time period, then assert a pin, then clear that pin. The CTIMER is almost an ideal way to do this. However the CTIMER peripheral's external outputs don't seem capable of setting then clearing the pin. Toggling won't work as I need to toggle the pin each time after a DMA transfer has taken place. Is there some way to accomplish this? I have a very convoluted work around but I am hoping I just missed a more straight forward solution.
Note: I cannot take advantage of the SCTimer as that peripheral has been purposed for a different process.
