H5[7:0]:
The H5[7:0] bits contain the cell header pattern inserted in the fifth octet (H5,
the HCS octet) of the idle/unassigned cell. Idle/unassigned cells are inserted
when the S/UNI-MPH detects that the transmit FIFO contains no outstanding
cells. H5[7] is the most significant bit and is the first bit transmitted. H5[0] is
the least significant bit. This register should be written with the correct
header check sequence value corresponding to the patterns written to the H1
- H4 octet Idle/Unassigned Cell Pattern Registers.
