H1[7:0]:
The H1[7:0] bits contain the cell header pattern inserted in the first octet (H1)
of the idle/unassigned cell. Idle/unassigned cells are inserted when the
S/UNI-MPH detects that the transmit FIFO contains no outstanding cells.
H1[7] is the most significant bit and is the first bit transmitted. H1[0] is the
least significant bit. This register should be set to 00H when transmitting the
standard idle/unassigned cell pattern.
