    Oh, I used to take Automatic Address Recognition as an extension of basic 8051 architecture.
    I've checked Intel 80C51's datasheet and found it included in the 8051 core.
    With AAR feature it'll be much easier to implement multi-uC communication with reduced sw. overhead.

    For LPC2148, of course it can implement AAR-like feature by PE interrupt and a few more lines of code.
