Patent ID: 8144890

Claim:
A method of loading ANR settings into an ANR circuit coupled to a bus external to the ANR circuit, the method comprising: placing the ANR circuit in a master mode on the bus; causing the ANR circuit to attempt to retrieve the ANR settings from an external storage device through the bus; in response to the attempt to retrieve the ANR settings from an external storage device through the bus being successful, loading the ANR settings into a storage device incorporated into the ANR circuit and placing the ANR circuit in a slave mode on the bus to enable the ANR circuit to accept data from an external processing device through the bus; in response to the attempt to retrieve the ANR settings from an external storage device through the bus not being successful, placing the ANR circuit in a slave mode on the bus to enable the ANR circuit to accept the ANR settings from an external processing device through the bus and awaiting receipt of the ANR settings from an external processing device through the bus for a selected period of time; and in response to the attempt to retrieve the ANR settings from an external storage device through the bus not being successful and in response to the ANR settings being received from an external processing device through the bus during the selected period of time after placing the ANR circuit in a slave mode on the bus, loading the ANR settings into the storage device incorporated into the ANR circuit and maintaining the ANR circuit in the slave mode on the bus to enable the ANR circuit to again accept data from an external processing device through the bus.
