The ARM9EJ-S processor can operate in three different states, each with a specific instruction
set:
In Jazelle state, all instruction Fetches are in words.
The operating state of the ARM9EJ-S core can be switched between:
• ARM state: 32-bit, word-aligned ARM instructions.
• THUMB state: 16-bit, halfword-aligned Thumb instructions.
• Jazelle state: variable length, byte-aligned Jazelle instructions.
• ARM state and THUMB state using the BX and BLX instructions, and loads to the PC
