Introduction
The Central Processing Unit (CPU) is responsible for using the information in the program mem-
ory (instructions) to control the operation of the device. Many of these instructions operate on
data memory. To operate on data memory, the Arithmetic Logical Unit (ALU) is required. In addi-
tion to performing arithmetical and logical operations, the ALU controls status bits (which are
found in the STATUS register). The result of some instructions force status bits to a value depend-
ing on the state of the result.
The machine codes that the CPU recognizes are show in
mnemonics that the MPASM uses to generate these codes).
