SPI and the frame interrupt
I'm interfacing the C5504 to an SPI flash device.
It seems the core needs to execute instructions on every character. It can't just set up a frame and then instruct the SPI to receive or transmit it. So why would one ever enable the frame interrupt?
Since no one has answered, it would seem that the SPI frame interrupt is a redundant feature of this DSP.
Since the TMS320C5504 does not implement DMA support for the SPI peripheral the CPU needs to handle each datum, the usefulness of the frame interrupt is diminished.
