maybe use named params here to help the reader:

regs = self.regRun(self.RUN_MODE_REGISTER_READBACK, info={}, reps=0)

Naming of the params is a good idea here but this should be done in a consistent way across the module. Should I add a commit that adds param names info and reps to all self.regRun() calls in the module?

I think it'd be a good idea to add param names throughout the module. Note that the param names for build1 and build7 are different.

I can never remember the preference of operators. I'd prefer to be explicit:
