PCMU Data Prefix Register
The data written to this register is read as the most significant byte of every
time slot read by the DSP from the PCMU frame buffers. Can be used for
quick access to the a/µ-law ROM, for conversion of compressed data
(received via the PCM interface) into linear value.
After reset this register contains the MSB of the base address of the a-law-
to-linear ROM table: E0
the PCMU Data Prefix Register should be programmed to E1
