Alert Response Address

The SMBus Alert Response interrupt pointer provides

quick fault identification for simple slave devices that

lack the complex, expensive logic needed to be a bus

master. Upon receiving an ALERT interrupt signal, the

host master can broadcast a Receive Byte transmission

to the Alert Response slave address (see the Slave

Addresses section). Then, any slave device that gener-

ated an interrupt, attempts to identify itself by putting its

own address on the bus (Table 4).

The Alert Response can activate several different slave

devices simultaneously, similar to the I

C General Call.

If more than one slave attempts to respond, bus arbitra-

tion rules apply, and the device with the lower address

code wins. The losing device does not generate an

acknowledge and continues to hold the ALERT line low

until cleared. (The conditions for clearing an alert vary
