DACnR[1:0]
This bit enables the Analog Out features of the board. 1 = DAC0/1 enabled.
0 = DAC0/1 disabled.
The
This bit determines the analog output mode of operation.
1 = Both DAC0 and DAC1 updated with data written to DAC0 data register. 0 = DACn updated with data written to DACn data register.
The
These bits select the independent gains/ranges for either DAC0 or DAC1. n=0 for DAC0 and n=1 for DAC1.
