before this long after STROBE edge, the recipient
receives no more than one additional data word.

assertion of STOP, when sender terminates a burst.
NOTES:
1 tUI, tMLI, tLI indicate sender-to-recipient or recipient-to-sender interlocks. That is, one agent (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 drive to which the parameter applies. For example, the sender shall
stop generating STROBE edges tRFS after negation of DMARDY. STROBE and DMARDY timing measurements are taken at
the connector of the sender. Even though the sender stops generating STROBE edges, the receiver may receive additional
STROBE edges due to propagation delays. All timing measurement switching points (low to high and high to low) are taken at
1.5 V.
