(6) SCSI interface (as initiator)

• Asynchronous transfer mode

(a) Input timing (target

→ initiator)

*1: The position number indicates the position in the waveform.

*2: The REQ “H”

→ ACK “L” time (tRQAK2) is compared with (tRQAKH + tAKRQL + tRQAK1) and the longer value is chosen.

Note: The input timing definition is not applied in the following cases.

• When the data register is FULL in the data phase

• When the final byte is being transferred
