2.2.2 SPECIAL FUNCTION REGISTERS

The Special Function Registers 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

give in Table 2-1.

The Special Function Registers can be classified into

two sets; core (CPU) and peripheral. Those registers

associated with the core functions are described in

detail in this section. Those related to the operation of

the peripheral features are described in detail in that

peripheral feature section.

x = unknown, u = unchanged, q = value depends on condition, - = unimplemented, read as ‘0’, Shaded locations are unimplemented,

read as ‘0’.

These registers can be addressed from either bank.

The upper byte of the program counter is not directly accessible. PCLATH is a holding register for PC<12:8> whose contents are

transferred to the upper byte of the program counter.

Other (non Power-up) Resets include: external Reset through MCLR and the Watchdog Timer Reset.

The IRP and RP1 bits are reserved. Always maintain these bits clear.

On any device Reset, these pins are configured as inputs.

This is the value that will be in the port output latch.

Reserved bits, do not use.

ECCPAS1 bit is not used on PIC16F716.
