PIC16F8X
PIC16CXX devices contain an 8-bit ALU and working The W register is an 8-bit working register used for ALU register. The ALU is a general purpose arithmetic unit. operations. It is not an addressable register. It performs arithmetic and Boolean functions between Depending on the instruction executed, the ALU may data in the working register and any register file. affect the values of the Carry (C), Digit Carry (DC), and The ALU is 8-bits wide and capable of addition, Zero (Z) bits in the STATUS register. The C and DC bits subtraction, shift and logical operations. Unless operate as a borrow and digit borrow out bit, otherwise mentioned, arithmetic operations are two's respectively, in subtraction. See the SUBLW and SUBWF complement in nature. In two-operand instructions, instructions for examples. typically one operand is the working register A simplified block diagram for the PIC16F8X is shown (W register), and the other operand is a file register or in Figure 3-1, its corresponding pin description is an immediate constant. In single operand instructions, shown in Table 3-1. the operand is either the W register or a file register.
