DS39605F-page 49 PIC18F1220/1320 5.9.2 SPECIAL FUNCTION REGISTERS The Special Function Registers (SFRs) are registers used by the CPU and peripheral modules for controlling the desired operation of the device. These registers are implemented as static RAM. A list of these registers is given in Table 5-1 and Table 5-2. The SFRs can be classified into two sets: those asso- ciated with the “core” function and those related to the peripheral functions. Those registers related to the “core” are described in this section, while those related to the operation of the peripheral features are described in the section of that peripheral feature. The SFRs are typically distributed among the peripherals whose functions they control. The unused SFR locations will be unimplemented and read as ‘0’s.
