These bit fields represent the most significant 16 bits of the internal
18-bit wide counters reflecting the number of cells currently stored
in the upstream/downstream cell storage RAM.
The CPU determines the buffer fill level with a granularity of 4 by
reading register UBufferOcc/DBufferOcc and left shifting the value
by 2:
fill_level(17:0):= (xBufferOcc(17:2) << 2)
