17. Special Function Registers
The direct-access data memory locations from 0x80 to 0xFF constitute the special function registers
(SFRs). The SFRs provide control and data exchange with the C8051F80x-83x's resources and peripher-
als. The CIP-51 controller core duplicates the SFRs found in a typical 8051 implementation as well as
implementing additional SFRs used to configure and access the sub-systems unique to the C8051F80x-
83x. This allows the addition of new functionality while retaining compatibility with the MCS-51™ instruc-
tion set. Table 17.1 lists the SFRs implemented in the C8051F80x-83x device family.
The SFR registers are accessed anytime the direct addressing mode is used to access memory locations
from 0x80 to 0xFF. SFRs with addresses ending in 0x0 or 0x8 (e.g., P0, TCON, SCON0, IE, etc.) are bit-
addressable as well as byte-addressable. All other SFRs are byte-addressable only. Unoccupied
addresses in the SFR space are reserved for future use. Accessing these areas will have an indeterminate
effect and should be avoided. Refer to the corresponding pages of the data sheet, as indicated in
Table 17.2, for a detailed description of each register.
Note: SFR Addresses ending in 0x0 or 0x8 are bit-addressable locations, and can be used with bitwise instructions.
