ST72264 and the RIM/SIM instructions

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.

Ah, yes in fact. Thank you
