14.3 Instruction Types
The MCU instructions fall into these five categories:
14.3.1 Register/Memory Instructions
These instructions operate on central processor unit (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.
