6.5.4 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 6-1 and Table 6-2.

The SFRs can be classified into two sets: those asso-

ciated with the âcoreâ function and those related to the

peripheral functions. Those registers related to the

âcoreâ 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 â0âs.
