Careful - I think I wrote that (duels have been fought over less).  I
think it's original title was:

  "IDT 3052 Microprocessor Family Software Reference Manual"

and the R3052 and family (includes at least R3051, R3081, R3041) are
all R3000-type CPUs.  So the book will describe "IsC" and not "DE" etc.

Bottom line, which I think everyone has got to: you need separate
#defines for R4000-type and R3000-type status registers, but it makes
sense to use the same names for the fields which are the same...
