15:0 SETTLECOUNT3 R/W 0x0000 Channel 3 Conversion Settling
The LDC will use this settling time to allow the LC sensor to
stabilize before initiation of a conversion on Channel 3.
If the amplitude has not settled prior to the conversion start, an
Amplitude error will be generated if reporting of this type of error
is enabled
