The byte values containing less than 8 valid bits are LSB justified. For example Info Page offset 0x90 is
an 8-bit object, whose three LSBs are bits [10:8] of the complete TEMP_85[10:0] 11-bit object. The Info
Page data objects are 2’s complement format and should be sign extended when read into a 16-bit data
type (see case _TEMP85 in the code example).
