Are you sure this isn't coming directly from a hardware data sheet or
description somewhere?  Based on the type, it really looks like it is.
If not, please document it properly that you have researched this in the
changelog text when resending.

Don't change variable names that reflect external names, that just makes
for more confusion over time.

thanks,

Same here, are you sure this doesn't come directly from the hardware
spec?
