Arithmetic Logical Unit (ALU)
PICmicro MCUs contain an 8-bit ALU and an 8-bit working register. The ALU is a general pur-
pose arithmetic and logical unit. It performs arithmetic and Boolean functions between the data
in the working register and any register file.
Figure 5-3: Operation of the ALU and W Register
The ALU is 8-bits wide and is 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). The other operand is a file
register or an immediate constant. In single operand instructions, the operand is either the W reg-
ister or a file register.
The W register is an 8-bit working register used for ALU operations. It is not an addressable reg-
ister.
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 bit
and a digit borrow out bit, respectively, in subtraction. See the SUBLW and SUBWF instructions for
examples.
