All timing measurement switching points (low to high and high to low) shall be taken at 1.5 V.
All signal transitions for a timing parameter shall be measured at the connector specified in the measurement
location column. For example, in the case of tRFS, both STROBE and –DMARDY transitions are measured at
the sender connector.
The parameter tCYC shall be measured at the recipient’s connector farthest from the sender.
The parameter tLI shall be measured at the connector of the sender or recipient that is responding to an
incoming transition from the recipient or sender respectively. Both the incoming signal and the outgoing
response shall be measured at the same connector.
The parameter tAZ shall be measured at the connector of the sender or recipient that is driving the bus but must
release the bus to allow for a bus turnaround.
