    (I don't know anything about ARM6 actually.)

    ARM610 supports six modes of operation:
    (1) User mode (usr): the normal program execution state
    (2) FIQ mode (fiq): designed to support a data transfer or channel process
    (3) IRQ mode (irq): used for general purpose interrupt handling
    (4) Supervisor mode (svc): a protected mode for the operating system
    (5) Abort mode (abt): entered after a data or instruction prefetch abort
    (6) Undefined mode (und): entered when an undefined instruction is executed

    Thumb technology starts from ARM7TDMI. There is no Thumb on ARM6 (ARMv3).
