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 via a single XFER_RDY frame.
• 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.
