11.4 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
11.4.1 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.
