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 CIP-51's resources and peripherals. The
CIP-51 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 MCU. This allows the addition of new
functionality while retaining compatibility with the MCS-51 instruction set. Table 9.3 lists the SFRs imple-
mented in the CIP-51 System Controller.
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, P1, SCON, 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 indetermi-
nate effect and should be avoided. Refer to the corresponding pages of the datasheet, as indicated in
Table 9.3, for a detailed description of each register.
Notes:
1. C8051F230/1/6 Do not have these registers.
2. C8051F221/231 Does not have this register (32 pin package).
3. On the C8051F206 and C8051F226/236 only.
4. On the C8051F206 only (12-bit ADC)
