Thanks to Jon, Gene, and Andy for your responses. I've been using EMC for 3-axis milling, but I've never had to get involved with HAL. I simply used the step config wizard to set things up, and everything worked.
I also set up the PWM spindle control in step config wizard. Am I correct to assume that the PWM output is different than the other outputs (like step X, dir X, etc.), in that I *must* write hal code to get it to work? Thanks!
