Timing Rule

1.5.1

Timing value

Table 1.15, 16, 17 give the timing required for operations on the SCSI bus.
Timing description
1 Arbitration delay
2 Bus clear delay
3 Bus free delay
4 Bus set delay
5 Bus settle delay
6 Cable skew (1)
7 Data release delay
8 DIFFSENS voltage filter time
9 Physical disconnection delay
10 Power on to selection (2)
11 QAS arbitration delay
12 QAS assertion delay
13 QAS release delay
14 QAS non-DATA phase REQ(ACK)
peiod
15 Reset delay
16 Reset hold time
Note: (1) Cable Skew is measured at each device connection with the transmitted skew subtracted from
the received skew. (2) This is a recommended time. It is not mandatory.
