Transmit Request
A Transmit Request is issued by the host to initiate the start of a new packet
transmission. A Transmit Request consists of the following three steps in exactly the
order shown:
1) The host writes a Transmit Command to the TxCMD register (PacketPage base + 0144h).
2) The host writes the transmit frame's length to the TxLength register (PacketPage base +
0146h).
3) The host reads BusST (Register 18) to see in the Rdy4TxNOW bit (Bit 8) is set.
