13.3 Instruction Types
The MCU instructions fall into the following five categories:
• Register/memory instructions
• Read-modify-write instructions
• Jump/branch instructions
• Bit manipulation instructions
• Control instructions
Instruction Types
13.3.1 Register/Memory Instructions
These instructions operate on CPU registers and memory locations. Most of them use two operands. One
operand is in either the accumulator or the index register. The CPU finds the other operand in memory.
