PIC16F8X
PIC16CXX devices contain an 8-bit ALU and working
register. The ALU is a general purpose arithmetic unit.
It performs arithmetic and Boolean functions between
data in the working register and any register file.
The ALU is 8-bits wide and capable of addition,
subtraction, shift and logical operations. Unless
otherwise mentioned, arithmetic operations are two’s
complement in nature. In two-operand instructions,
typically one operand is the working register
(W register), and the other operand is a file register or
an immediate constant. In single operand instructions,
the operand is either the W register or a file register.

STATUS reg
The W register is an 8-bit working register used for ALU
operations. It is not an addressable register.
Depending on the instruction executed, the ALU may
affect the values of the Carry (C), Digit Carry (DC), and
Zero (Z) bits in the STATUS register. The C and DC bits
operate as a borrow and digit borrow out bit,
respectively, in subtraction. See the SUBLW and SUBWF
instructions for examples.
A simplified block diagram for the PIC16F8X is shown
in Figure 3-1, its corresponding pin description is
shown in Table 3-1.
