Transfer in synchronous mode | Fujitsu MCP3130SS, MCP3064SS guide

SCSI BUS

4)Starting with the rise of the ACK pulse, the TARG reads data on the data bus (DB7 to DB0, P) within the Hold time.

(3)Time monitoring of ACK response wait

When the ODD operates as a TARG, wait time for ACK response to REQ can be monitored.
