Why not just use CFGCHIP_REG(n) directly?
I considered that, but I went this way because A) the TRM uses, for example,
"CFGCHIP2", so I wanted to keep "CFGCHIP" and "2" together
I'd just drop the _REG suffix.
and B) this tells
you how many CFGCHIP registers there are, i.e. there is no CFGCHIP5_REG.
You can tell that in a comment. Having a parametrized macro and using it
to just #define more macros doesn't appeal to me at all...
