Fig.7 UART multiprocessor communication, automatic address recognition.
UART modes 2 or 3 and SM2 = 1: there is an interrupt if REN = 1, RB8 = 1 and received address is equal to programmed address.
When own address is received, reset SM2 to receive the data bytes. When all data bytes are received, set SM2 to wait for the next address.
