    Table 6 : Error Code Definition (R0 content after STEAK execution)
    Note: The Flash Embedded STEAK Algorithms
    require at least 50 words on the Internal
    System Stack for proper operation. The
    program itself verifies that there is enough
    free space on the System Stack before
    performing a programming or erasing
    operation, by computing the Word number
    between Stack Pointer (SP) and Stack
    Overflow register (STKOV ).
    The MDH, MDL and MDC register content
    are modified.
    Registers R0 to R4 are used as Input Data
    for STEAK, and are modified as explained
    above (Return Values).
    Registers R5 to R15 are used internally by
    STEAK, but preserved on entry and
    restore on exit of STEAK.
    IT IS VERY IMPORTANT TO TAKE INTO
    ACCOUNT THE FACT THAT STEAK
    USES UP TO 50 WORDS ON THE SYS-
    TEM
    STACK.
    TO
    PREVENT
    ANY
    ABNORMAL SITUATION, IT IS VERY
    IMPORTANT
    TO
    INITIALIZE
    COR-
    RECTLY THE STACK SIZE TO AT LEAST
    64 WORDS, AND TO CORRECTLY INI-
    TIALIZE REGISTER STKOV.
