Notes:

 

 

 

 

 

 

 

1)tUI, tMLI and tLI indicate sender -to-recipient or recipient-to-sender interlocks, that is, one agent (either sender or recipient) is waiting for the other agent to respond with a signal before proceeding. tUI is an unlimited interlock, that has no maximum time value. tMLI is a limited time-out that has a defined minimum. tLI is a limited time-out, that has a defined maximum.

2)All timing parameters are measured at the connector of the device to which the parameter applies. For example, the sender shall stop generating STROBE edges tRFS after the negation of DMARDY-. Both STROBE and DMARDY- timing measurements are taken at the connector of the sender.

3)All timing measurement switching points (low to high and high to low) are to be taken at 1.5 V.
