Notes:
1) All timing measurement switching points (low to high and high to low) shall be taken at 1.5 V.
2) 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.
3) The parameter tCYC shall be measured at the recipient’s connector farthest from the sender.
