Header0 register must contain the isochronous header or the first quadlet of an asynchronous header if in
header insert mode. If not in header insert mode or if in receive mode, this register will be updated with the
received header. This register is write protected such that it cannot be written to unless automatic header
insert mode is enabled and DM is in transmit mode(i.e.,DMHDR=0 and DMRX=0). The power-up reset value
of this register =
0000_0000
