I've been searching the datasheet for an answer with no luck. Hopefully someone will be able to help.
I am writing a SPI TX complete interrupt routine that will function as a state machine to perform a 4 byte transfer then disable the interrupt. I desire to enable then manually trigger this interrupt (start the state machine) within a timer routine.
In the past, I've seen where there were methods for manually triggering the interrupt such as writing to the interrupt flag register in some cases, etc. I cannot find in the datasheet how to manually trigger the interrupt. Is it possible to simply call the interrupt routine like you would call a function? I suppose I could enable the interrupt then write dummy data to start interrupt process but that doesn't appeal to me.
Thanks for any assistance you may offer.
