manual abstract


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. 5-98 C141-E050-02EN 5.6 Timing 5.6.4.3 Sustained Ultra DMA data in burst 5.6.4.2 contains the values for the timings for each of the Ultra DMA Modes. Note: DD (15:0) and DSTROBE are shown at both the host and the device to emphasize that cable setting time as well as cable propagation delay shall not allow the data signals to be considered stable at the host until some time after they are driven by the device. Figure 5.14 Sustained Ultra DMA data in burst C141-E050-02EN 5-99 Interface 5.6.4.4 Host pausing an Ultra DMA data in burst 5.6.4.2 contains the values for the timings for each of the Ultra DMA Modes. Notes: 1) The host may assert STOP to request termination of the Ultra DMA burst no sooner than tRP after HDMARDY- is negated. 2) If the tSR timing is not satisfied, the host may receive zero, one or two more data words from the device.

Note: The definitions for the STOP, HDMARDY- and DSTROBE signal lines are no longer in effect after DMARQ and DMACK are negated.

Note: The definitions for the STOP, DDMARDY- and HSTROBE signal lines are not in effect until DMARQ and DMACK are asserted.
