Transfer is complete. Successful completion generates a Bus Service
interrupt. For DMA Transfer Information, the transfer is complete
when the transfer counter decrements to zero, the FIFO is empty and
the target asserts REQ/ for the next byte. For non-DMA Transfer
Information in which the FSC is sending bytes to the SCSI bus, the
transfer is complete when the FIFO empties and the target asserts
REQ/ for the next byte. For non-DMA Transfer Information in which
the FSC is receiving bytes from the SCSI bus, transfer is complete
after one byte is received and the target asserts REQ/ for the next
byte. Thus non-DMA Transfer Information commands generate an
interrupt for every byte received.
Note:
lists the Initiator commands.
Initiator Commands
For synchronous transfer, DMA must be used. The FSC
continues to transfer information until one of the following
terminating events occurs:
