SPECIAL FUNCTION REGISTERS
All registers, except the program counter and the four general purpose register banks, reside in the special func-
tion register area.
The 28 special function registers (SFR) include pointers and registers that provide an interface between the CPU
and the other on-chip peripherals. There are also 128 directly addressable bits within the SFR area.
All SFRs are listed in Table 1, Table 2, and Table 3.
In Table 1 they are organized in numeric order of their addresses. In Table 2 they are organized in groups which
refer to the functional blocks of the HMS99C51S/52S/54S/56S/58S. Table 3 illustrates the contents of the SFRs
