#187439 - at89s51 mode 2 multiprocessor environment.
I am making a system with one master and three slaves. but i have done basic communication in mode 1 but i found (in theory ) it would be much better if i did it in mode 2.

now question is that my model of 8051 doesnt have sddr or saden for automatic recognition. this is what i have in mind, just need to know if its right.

master in mode 2 sm2=1

slave in mode 2 sm2=1
adress in r2
ri=1, compares recieved sbuff with r2
if matching set sm2=0

master in mode 2 sm2=1

slave in mode 2 sm2=0
ri=1, saves data

is this the right way to match adresses without saddr etc?
