8.1.2.3.3 Power Sequence Editing Tools

In addition to the four editing tools for each individual command (update, move up, move down, delete), there are four tools available for editing the power sequence in its entirety. From left-to-right, the tools are export power sequence, copy sequence, paste sequence, and reverse sequence (see Figure 8-21). The copy, paste, and reverse sequence tools create a convenient way to copy a power sequence, for example, a power-on sequence, and to paste in a new sequence, then reverse to create a power-off sequence.

Note: The reversal is not applied to the TRIG_MASKS as these are always intended to be at the end of the sequence. The reversal is only of the order of the commands and not the timing relationship or polarity; enable does not become disable.

The export power sequence provides a more complete graphical view which can be exported. From this view the user has the ability to provide inputs for the conditional WAIT command and generate timing diagrams for different conditions. As shown in Figure 8-22, either the true condition of the timeout can be selected and the timing diagram is updated appropriately.

Note: Texas Instruments recommends exporting power sequences to confirm that the timing aligns with system requirements.
