The Reference DAC can interface the selected load through a buffer. The buffer must be enabled when the Reference DAC interfaces an external load. It is not recommended to interface internal loads with the buffer.
To enable the buffer, set AUX_ANAIF:DACCTL.DAC_BUFFER_EN to 1. To enable the buffer in LPM (Low Power Mode) also set AUX_ANAIF:LPMBIASCTL.EN to 1 to enable the bias module. The buffer cannot be used when AUX requests Power-Down operational mode.
