The 16-bit data word for the TLV5638 consists of two parts:
D Program bits
(D15..D12)
D New data
(D11..D0)

12 Data bits
SPD: Speed control bit
1
→ fast mode
0
→ slow mode
PWR: Power control bit
1
→ power down
0
→ normal operation
The following table lists the possible combination of the register select bits:

The meaning of the 12 data bits depends on the register. If one of the DAC registers or the BUFFER is selected,
then the 12 data bits determine the new DAC value:
