6. Special Function Registers
The W79E(L)633 uses Special Function Registers (SFR) to control and monitor peripherals. The SFR
reside in register locations 80-FFh and are only accessed by direct addressing. The W79E(L)633
contains all the SFR present in the standard 8051/52, as well as some additional SFR, and, in some
cases, unused bits in the standard 8051/52 have new functions. SFR whose addresses end in 0 or 8
(hex) are bit-addressable. The following table of SFR 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 reads high.

1. The SFRs in the column with dark borders are bit-addressable
2. The table is condensed with eight locations per row. Empty locations indicate that these are no registers at these addresses.
When a bit or register is not implemented, it will read high.
