10.4.9. Starvation Control

The controller implements a starvation counter to ensure that lower-priority requests are not forgotten as higher-priority requests are reordered for efficiency.

In starvation control, a counter is incremented for every command served. You can set a starvation limit, to ensure that a waiting command is served immediately upon the starvation counter reaching the specified limit.

For example, if you set a starvation limit of 10, a lower-priority command is treated as high priority and served immediately, after ten other commands are served before it.
