11.3 Instruction Types
The MCU instructions fall into five categories:
1. Register/memory instructions
2. Read-modify-write instructions
3. Jump/branch instructions
4. Bit manipulation instructions
5. Control instructions
Instruction Types
11.3.1 Register/Memory Instructions
Most of these instructions use two operands. One operand is in either the accumulator or the index
register. The CPU finds the other operand in memory. Table 11-1 lists the register/memory instructions.
