Range Comparator Lower Threshold Registers (ADC12Bn_RCOL0
to 7)
When the 8-bit range comparator mode (ADC12Bn_CTRL.FRCMD = "0"), these registers are used for
8-bit range comparator.
If the 12-bit range comparator mode (ADC12Bn_CTRL.FRCMD = "1"), these registers are not used.
These registers specify the lower threshold values that can be selected for the 8-bit range comparator to
which the output of the A/D Converter is compared. Only ADC12Bn_RCOL0 is described here. Other
registers (ADC12Bn_RCOL1,...,ADC12Bn_RCOL6, ADC12Bn_RCOL7) have similar bit fields.

[bit7:0] RCOL[7:0] : Range Comparator Lower Threshold value
The RCOL bits define the lower comparison threshold of the range comparator 0.
The lower comparator compares the upper 8 bits of the A/D conversion result. If the value is lower than
RCOL[7:0], then the conversion result is outside range.
Selection of one of eight available range comparator threshold values for the logical channel is
configured by corresponding ADC12Bn_CHCTRL0 to 63.RCSEL[2:0] bit fields.
