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.

Legend:
Shaded boxes = unimplemented or unused,
—
= unimplemented, read as ’0’ (if applicable)
x
= unknown,
u
= unchanged,
q
= see the tables in Section 8.7 for possible values.
The upper byte of the Program Counter is not directly accessible. See Section 4.6
for an explanation of how to access these bits.
Other (non power-up) resets include external reset through MCLR, watchdog timer and wake-up on pin change reset.
If reset was due to wake-up on pin change then bit 7 = 1. All other resets will cause bit 7 = 0.
