Information registers
The device information registers can be read by using OpCode ‘11’. After shifting out the GSB the 8-bit wide
payload is transmitted. By reading the device information registers a communication width, which is minimum 16
bits plus a multiple by 8 can be used. After shifting out the GSB followed by the 8-bit wide payload a series of ‘0’
is shifted out at the SDO.
