A read operation is accomplished when the address byte is 0x02. Follow the read operation with a no-operation (NOP) command to clock out an addressed register, as shown in Figure 7-2. To read from a register, the address byte and data word is as shown in Table 8-14. The read register value is output MSB first on SDO on successive falling edges of SCLK.
|ADDRESS BYTE||DATA WORD|
|BIT 15:BIT 6||BIT 5:BIT 0|
|0x02||X (don't care)||Register read address (see Table 8-15)|
Table 8-15 shows the register read addresses available on the DACx760 devices.
|XX XX00||Read status register|
|XX XX01||Read DAC data register|
|XX XX10||Read control register|
|00 1011||Read configuration register|
|01 0011||Read DAC gain calibration register|
|01 0111||Read DAC zero calibration register|
