General Instruction Format
Central Processing Unit (CPU)
Instruction Clock
The Mid-Range MCU instructions can be broken down into four general formats as shown in
Figure
opcode size is what allows 35 instructions to be implemented.
Figure 5-1: General Format for Instructions
The CPU can be thought of as the “brains” of the device. It is responsible for fetching the correct
instruction for execution, decoding that instruction, and then executing that instruction.
The CPU sometimes works in conjunction with the ALU to complete the execution of the instruc-
tion (in arithmetic and logical operations).
The CPU controls the program memory address bus, the data memory address bus, and
accesses to the stack.
Each instruction cycle (T
