I'm working on a project where I'm using a PIC18F14K50 to drive a Hittite HMC704LP4E frequency synthesizer via SPI in HMC Mode. I'm trying to make sense of the Hittite documentation. Am I understanding it correctly that I DON'T send whole bytes to the Hittite chip, just strings of bits (in non-multiples of 8)? I don't have an eval board to work with, and I'm just the "code guy." Does anyone else have experience working with these?
