SPECIAL FUNCTION REGISTERS
The Special Function Registers (SFRs) are registers
used by the CPU and peripheral functions to control the
operation of the device (see Table 4-1).
The Special Function Registers can be classified into
two sets. The Special Function Registers associated
with the “core” functions are described in this section.
Those related to the operation of the peripheral
features are described in the section for each
peripheral feature.

Note
1:
The upper byte of the Program Counter is not directly accessible. See Section 4.6 “Program Counter” for an explanation of
how to access these bits.
