ADC_OFFSET[7:0] ADC_OFFSET is an 8-bit compressed value representing a 16-bit value added to all
measurements. Since most measurements are relative measurements involving a
arithmetic subtraction and can result in a negative value. Since 0xFFFF is treated as
an overrange indicator, the ADC_OFFSET is added so that the values reported in
the I 2 C register map are never confused with the 0xFFFF overrange indicator.
For example:
0x60: Measurements have a 64-code offset
0x70: Measurements have a 128-code offset
0x80: Measurements have a 256-code offset
Please refer to AN498 “Si114x Designer ’s Guide”, Section 5.4 “Compression
Concept.”
