PRODUCTION DATA
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; see Figure 7-2. To read from a register, the address byte and data word is as shown in Table 8-9. The read register value is output MSB first on SDO on successive falling edges of SCLK.
ADDRESS BYTE (HEX) |
DATA WORD | |
---|---|---|
BIT 15:BIT 6 | BIT 5:BIT 0 | |
02 | X (don't care) | Register read address (see Table 8-10) |
Table 8-10 shows the register read addresses available on the DACx750 devices.
