PIC16F630/676
2.2.2 SPECIAL FUNCTION REGISTERS
The Special Function Registers are registers used by
the CPU and peripheral functions for controlling the
desired operation of the device (see Table 2-1). These
registers are static RAM.
The special registers can be classified into two sets:
core and peripheral. The Special Function Registers
associated with the âcoreâ are described in this section.
Those related to the operation of the peripheral
features are described in the section of that peripheral
feature.
