Are you planning on putting some sort of IC in between, like a small
microcontroller or a CPLD? Generating PWM in software, particularly a
non-RTOS, is not a great idea to begin with. You'll need to look at what
tolerances you have on that PWM, for one thing, in terms of how late the edges
are allowed to be, standard deviation, etc.
But I think people have already answered the SPI part for you.
