5.2 Register description

5.2.1 Status registers

[0x00-0x01] - DeviceH and DeviceL

These registers provide read only information to identify the sensor type that has been coded as a

12-bit number and a 4-bit mask set revision identifier. The device identification number for VV6501

is 501 equivalent to 0001 1111 0101

. The initial mask revision identifier is 0 equivalent to 0000

[0x02] - Status0
