OPAxEN: OPAx Enable bit
1 = OPAx is enabled
0 = OPAx is disabled
Unimplemented: Read as ‘0’
OPAxUGM: OPAx Unity Gain Mode Enable bit
1 = OPAx is in Unity gain mode
0 = OPAx is not in Unity gain mode - operates as a three-terminal op amp
OPAxNCH<1:0>: OPAx Negative Input Source Selection bit
11 = OPAx- connects to FVR_buffer1
10 = OPAx- connects to DAC1_output
0x = OPAx- connects to OPAxIN- pin
OPAxPCH<1:0>: OPAx Positive Input Source Selection bit
11 = OPAx+ connects to FVR_buffer1
10 = OPAx+ connects to DAC1_output
01 = OPAx+ connects to SLOPE_output
00 = OPAx+ connects to OPAxIN+ pin
