These registers contain the number of items (64-bit words) remaining to
be read from the Audio ES channel buffer to the selected Audio Decoder.
The LSB should be read first, since this captures the next significant byte
and MSB in Registers 138 and 139. These should then be read
immediately to ensure that the correct captured value is read.
These registers contain the number of items (64-bit words) remaining to
