Multiprocessor Communications
The multiprocessor communication feature is enabled in modes 2 and 3 when the SM2
bit is set in the SCON SFR for a serial port. In multiprocessor communication mode, the
9th bit received is stored in RB8 and, after the stop bit is received, the serial port
interrupt is activated only if RB8 = 1. A typical use for the multiprocessor
communication feature is when a master wants to send a block of data to one of several
slaves. The master first transmits an address byte that identifies the target slave. When
transmitting an address byte, the master sets the 9
th
bit to 1; for data bytes, the 9th bit is
0.
When SM2 = 1, no slave will be interrupted by a data byte. However, an address byte
interrupts all slaves so that each slave can examine the received address byte to
determine whether that slave is being addressed. Address decoding must be done by
software during the interrupt service routine. The addressed slave clears its SM2 bit and
prepares to receive the data bytes. The slaves that are not being addressed leave the SM2
bit set and ignore the incoming data bytes.
