• Bits 7:4 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bits 3:0 - CHDATA[11:8]: DAC Conversion Data Register Channel 0, 4 MSB
These bits are the 4 MSB of the 12-bit value to convert to channel 0 in right-adjusted mode.
• Bits 7:0 - CHDATA[11:4]: DAC Conversion Data Register Channel 0, 8 MSB
These bits are the 8 MSB of the 12-bit value to convert to channel 0 in left-adjusted mode.
• Bits 7:0 - CHDATA[7:0]: DAC Conversion Data Register Channel 0, 8 LSB
These bits are the 8 LSB of the 12-bit value to convert to channel 0 in right-adjusted mode.
• Bits 7:4 - CHDATA[3:0]: DAC Conversion Data Register Channel 0, 4 LSB
These bits are the 4 LSB of the 12-bit value to convert to channel 0 in left-adjusted mode.
• Bits 3:0 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
