(5) DMA interface
The DMA access timing described in this section is not applicable in the following cases.
During SCSI input, when the data buffer is EMPTY or when one byte is stored
During SCSI output, when the data buffer is FULL or when 31 bytes are stored
When a parity error is detected (target)
When an error which pauses the transfer occurs at the SCSI interface
80 series handshake mode
