ADC: ADC Offset Trim in Different Modes
B, C
A different offset trim is required when switching between 12-bit and 16-bit resolution and when switching between single-ended and differential signaling mode.
Whenever setting the resolution or signal mode of the ADC, use the “AdcSetMode” function in C2000Ware. This will ensure the correct trims are loaded into the offset trim register. Note that on start-up, trims will be loaded for 12-bit, single-ended operation.
