Table 27-19. LJSRR Field Descriptions
The left justified, signed format corresponds to a half-scale, offset binary, two's complement
data format. Conversion values corresponding to 1/2 full scale, 0x0200, or higher are
interpreted as positive values and have a sign bit of 0. An unsigned, right justified conversion
of 0x0200 would be represented as 0x0000 in this signed register, where the sign = 0 and the
result = 0. For an unsigned, right justified conversion of 0x3FF (full range or V
equivalent in this register would be 0x7FC0, sign = 0 and result = 0x1FF. For an unsigned, right
justified conversion of 0x0000 (V
sign = 1 and result = 0x000, a two's complement value representing –512.
The conversion result is signed, left-justified data.
