SPi Master Tx Interrupts
I'm having difficulty getting the interrupts in the SPI master to work. Each time SPIM transmits, I want it to trigger an the soc input of an ADC. The problem is that the interrupt doesn't seem to fire. I tried isolating the problem in the design, attached.
In the schematic editor, I have enabled the TxFIFO Empty interrupt, and have not enabled the Tx internal interrupt, as is done in CE56273. Assuming my ISR connected to the Tx interrupt pin is configured correctly, the interrupt is never triggered. I have also tried to implement this with for the Byte/word transmission complete interrupt, which does not seem to work, either.
I'd appreciate any suggestions regarding where to go next with the attached project. Thanks
