MODE

DACnR[1:0]

This bit enables the Analog Out features of the board. 1 = DAC0/1 enabled.

0 = DAC0/1 disabled.

The power-on state of this bit is 0.

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 power-on state of this bit is 0.

These bits select the independent gains/ranges for either DAC0 or DAC1. n=0 for DAC0 and n=1 for DAC1.

DACnR1	DACnR0	Range	LSB Size

0	1	Bipolar 10V	4.88mV

1	0	Unipolar 5V	610uV

1	1	Unipolar 10V	1.22mV
