• SLEEP: Sleep Mode
0 = Normal Mode: The DAC Core and reference voltage circuitry are kept ON between conversions.
After reset, the DAC is in normal mode but with the voltage reference and the DAC core off. For the first conversion, a
startup time must be defined in the STARTUP field. Note that in this mode, STARTUP time is only required once, at start
up.
1 = Sleep Mode: The DAC Core and reference voltage circuitry are OFF between conversions.
• FASTWKUP: Fast Wake up Mode
0 = Normal Sleep Mode: The sleep mode is defined by the SLEEP bit.
1 = Fast Wake Up Sleep Mode: The voltage reference is ON between conversions and DAC Core is OFF.
• REFRESH: Refresh Period
• USER_SEL: User Channel Selection
• TAG: Tag Selection Mode
