7. SPECIAL FUNCTION REGISTERS
The W77E058 uses Special Function Registers (SFRs) to control and monitor peripherals and their
Modes.
The SFRs reside in the register locations 80-FFh and are accessed by direct addressing only. Some
of the SFRs are bit addressable. This is very useful in cases where one wishes to modify a particular
bit without changing the others. The SFRs that are bit addressable are those whose addresses end in
0 or 8. The W77E058 contains all the SFRs present in the standard 8052. However, some additional
SFRs have been added. In some cases unused bits in the original 8052 have been given new
functions. The list of SFRs is as follows. The table is condensed with eight locations per row. Empty
locations indicate that there are no registers at these addresses. When a bit or register is not
implemented, it will read high.
