The setting applied to MODE_SEL (register 00h[3]; see
whether the DAC1205D650 operates in the Dual-port mode or in the Interleaved mode
(see
Table 30.
The data input for Dual-port mode operation is shown in
DAC has its own independent data input. The data enters the input latch on the rising
edge of the internal clock signal and is transferred to the DAC latch.
The data input for Interleaved mode operation is shown in
