 		 #129026 - it does - and it does not
Responding to: ???'s previous message
I'm a little confused with this statement. I thought that SM2 turns on the address recognition.
what SM2 teuns on is not "turn on the address recognition" what it does is (quoting a data sheet):

5 SM2 Enables the multiprocessor communication feature in Modes 2 and 3. In Mode 2 or 3, if SM2 is set to 1, then Rl will not be activated if the received 9th data bit (RB8) is 0.

so, in other words, If SM2 is set at the receiving end, no interrupt will occur unless the 9th bit is set by the transmitter (the transmitter set TB8).

If you leave SADDR and SADEN in the default state there is no "address recognition", only "this is an address byte, because 9th bit is set, recognition"
