Special Function
Registers
The Special Function Registers (SFRs) of the TSC80251G2D derivatives fall into the
categories detailed in Table 1 to Table 9.
SFRs are placed in a reserved on-chip memory region S: which is not represented in the
data memory mapping (Figure 5). The relative addresses within S: of these SFRs are
provided together with their reset values in Table . They are upward compatible with the
SFRs of the standard 80C51 and the Intel’s 80C251Sx family. In this table, the C251
core registers are identified by Note 1 and are described in the TSC80251 Program-
mer’s Guide. The other SFRs are described in the TSC80251G1D Design Guide. All the
SFRs are bit-addressable using the C251 instruction set.

file.
