Maximum Burst Size
For read data, this field contains the maximum amount of data in 512-byte
increments that is transferred during a connection by an SSP target port
per I_T_L_Q nexus without transferring at least one frame for a different
I_T_L_Q nexus.
For write data, the value shall specify the maximum amount of data that
an SSP target port requests through a single XFER_RDY frame.
The value 0000h in this field specifies that there is no maximum burst size.
First Burst Size
If the ENABLE FIRST BURST bit in the COMMAND frame is set to zero,
then the FIRST BURST SIZE field is ignored.
If the ENABLE FIRST BURST bit in the COMMAND frame is set to one,
then the value in the FIRST BURST SIZE field contains the maximum
amount of write data in 512-byte increments that may be sent by the SSP
initiator port to the SSP target port without having to receive an
XFER_RDY frame from the SSP target port.
