The SFRs are listed in
. The base address for the SFRs is 00100h. Many of the bits inside the
SFRs are described in other chapters throughout this user's guide. These bits are marked with a note and
a reference. See the specific chapter of the respective module for details.
NOTE:
All registers have word or byte register access. For a generic register
ANYREG
