GENERAL CALL
The General Call is a method that the “master” device
can communicate with all other “slave” devices. In a
multi-master application, the other master devices are
operating in Slave mode. The General Call address
has two documented formats. These are shown in
The MCP47X6 has two General Call commands. The
function of these commands are:
Reset the device(s) (Software Reset)
Wake-Up the device(s)
For details on the operation of the MCP47X6’s General
FIGURE 5-11:
General Call Formats.
Note:
Only one General Call command per issue
of the General Call control byte. Any
additional General Call commands are
ignored and Not Acknowledged.
