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
Figure
in this figure as well.
This will allow customers to have multiple I
Potentiometers on the bus and have them operate in a
synchronous fashion (analogous to the DAC Sync pin
functionality). If these MCP45XX/46XX 7-bit com-
mands conflict with other I
the customer will need two I
the devices are on the correct bus for their desired
application functionality.
Dual Pot devices can not update both Pot0 and Pot1
from a single command. To address this, there are
General Call commands for the Wiper 0, Wiper 1, and
the TCON registers.
