H2[7:0]:
The H2[7:0] bits contain the cell header pattern inserted in the second octet
(H2) of the idle/unassigned cell. Idle/unassigned cells are inserted when the
S/UNI-MPH detects that the transmit FIFO contains no outstanding cells.
H2[7] is the most significant bit and is the first bit transmitted. H2[0] is the
least significant bit. This register should be set to 00H when transmitting the
standard idle/unassigned cell pattern.
