Peripheral SFRs

Locations 1F00–1FDFH provide access to the peripheral SFRs (see Table 4-6 on page 4-10). Lo-
cations in this range that are omitted from the table are reserved. The peripheral SFRs are I/O con-
trol registers; they are physically located in the on-chip peripherals. These peripheral SFRs can
be windowed and they can be addressed either as words or bytes, except as noted in the table.
