Clear Address Command

The clear address command will clear the device ID

byte from all devices on the bus and will enable all

devices to respond to the Assign Address command.

The master must end the command by sending an ack

after 8 don’t care bits have been transmitted, followed

by a Stop bit. Sending the Stop bit in any other position

of the command will result in the command aborting

and the device releasing the bus.
