SPECIAL FUNCTION REGISTERS
The Special Function Registers (SFRs) are registers
used by the CPU and peripheral functions to control
the operation of the device (Table 4-1).
The special 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:
If reset was due to wake-up on pin change, then bit 7 = 1. All other rests will cause bit 7 = 0.
Note 2:
Other (non-power-up) resets include external reset through MCLR, watchdog timer and wake-up on pin change reset.
