Bit Field Type Reset Description
15:0 DACx-DATA[15:0] R/W 0x0000 or 0x8000 Stores the 16-, 14- or 12-bit data to be loaded to DACx in MSB aligned straight binary format. The default value is zero-code for the DACx0508Z devices and midscale-code for the DACx0508M ones.
Data follows the format below:
DAC80508: \{ DATA[15:0] \}
DAC70508: \{ DATA[13:0], x, x \}
DAC60508: \{ DATA[11:0], x, x, x, x \}
x – Don’t care bits
