A whole bunch of files in this project had DOS line endings. This is due
to how I started working on it on a Windows machine with little Git
experience. Now it's inconsistent so I'm fixing it.
It does add some complexity to the code. I may be going through a chain of calls just to turn the CS pin on, for instance. Hopefully I'm not going too crazy with this.
Anyway, this means that I can control the ports from a SIMM electrical test routine using the same types of functions that the actual programming controlling code would use, without having to duplicate a bunch of port definitions and bit manipulation. I made sure to add all the functions I can think of needing to the ports module. We'll see if I got them all!
