    Hello,

    What do exactly the RIM and SIM instructions on the ST72264 mcu ?

    The code register CC contains two IT bits: I0 and I1, while 'standart' SMI/RMI behaviour is only specified for the former I (and now I0) bit.

    Thank you

    SIM writes I1:0 = 11 (level 3)

    RIM writes I1:0 = 10 (level 0)

    This is specified in the datasheet ''instruction set'' chapter.
