5.5.1 DeviceH [000_00002] and DeviceL [000_ 00012]

These registers provide read only information that identifies the sensor type that has been coded as a 12bit number

and a 4bit mask set revision identifier. The device identification number for VV6404 is 404 i.e. 0001 1001 01002. The

initial mask revision identifier is 0 i.e. 00002.
