Notes:
1. Characteristics are symmetrical about analog zero with sign bit = 0 for negative values.
2. Digital code includes inversion of even-numbered bits. Other available formats include inversion of odd bits, inversion
of all bits, or no bit inversion. See "PCM Companding" on page 75 for more details.
