20.2.1 DAC 1 Output Register (DAC1OUT, M3[02h])

Bits 15:10: Reserved

Bits 9:0: DAC 1 Output Value. Bits 9:0 in this register set the voltage output value for the DAC1 channel between zero

(DAC1OUT[9:0] = 0000000000b) and full scale (DAC1OUT[9:0] = 1111111111b). For this register value to be effective,

one or both of the following two register bits in DACEN must be set.

• If DACEN.0 (DACEN1) is set to 1, the DAC1OUT value is output to differential pins RIN+/RIN-.

• If DACEN.4 (DACOUT1) is set to 1, the DAC1OUT value is output to pin DAC1.

20.2.2 DAC 2 Output Register (DAC2OUT, M3[03h])

Bits 15:10: Reserved

Bits 9:0: DAC 2 Output Value. Bits 9:0 in this register set the voltage output value for the DAC2 channel between

zero (if DAC2OUT[9:0] = 0000000000b) and full scale (DAC2OUT[9:0] = 1111111111b). For this register value to be

effective, one or both of the following two register bits in DACEN must be set.

• If DACEN.1 (DACEN2) is set to 1, the DAC2OUT value is output to differential pins LIN+/LIN-.

• If DACEN.5 (DACOUT2) is set to 1, the DAC2OUT value is output to pin DAC2.
