Register 48: ADC Digital Comparator Range 1 (ADCDCCMP1), offset 0xE44
Register 49: ADC Digital Comparator Range 2 (ADCDCCMP2), offset 0xE48
Register 50: ADC Digital Comparator Range 3 (ADCDCCMP3), offset 0xE4C
Register 51: ADC Digital Comparator Range 4 (ADCDCCMP4), offset 0xE50
Register 52: ADC Digital Comparator Range 5 (ADCDCCMP5), offset 0xE54
Register 53: ADC Digital Comparator Range 6 (ADCDCCMP6), offset 0xE58
Register 54: ADC Digital Comparator Range 7 (ADCDCCMP7), offset 0xE5C
This register defines the comparison values that are used to determine if the ADC conversion data
falls in the appropriate operating region.
Note: The value in the COMP1 field must be greater than or equal to the value in the COMP0 field
or unexpected results can occur.
If the RES bit in the ADCCTL register is clear, selecting 10-bit resolution, use only bits [25:16]
in the COMP1 field and bits [9:0] in the COMP0 field; otherwise unexpected results can occur.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Compare 1
The value in this field is compared against the ADC conversion data.
The result of the comparison is used to determine if the data lies within
the high-band region.
Note that the value of COMP1 must be greater than or equal to the value
of COMP0.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
