2.13. Companding
The ProSLIC supports both µ-255 Law and A-Law companding formats in addition to linear data. These 8-bit
companding schemes follow a segmented curve formatted as sign bit, three chord bits, and four step bits. µ-255
Law is more commonly used in North America and Japan, while A-Law is primarily used in Europe. Data format is
selected via the PCMF register. Tables 34 and 35 define the µ-Law and A-Law encoding formats.
