The Special Function Registers (SFRs) are registers
used by the CPU and peripheral functions to control
the operation of the device (Table 4-1).

SPECIAL FUNCTION REGISTERS
q = depends on condition.
If reset was due to wake-up on pin change, then bit 7 = 1. All other rests will cause bit 7 = 0.
Other (non-power-up) resets include external reset through MCLR, watchdog timer and wake-up on pin change reset.

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.
