Figure 25-11 Channel Injection with Inject-Wait
Figure 25-12 shows the behavior of conversion requests generated by “Channel
Injection” using the Cancel-Inject-Repeat feature. In the first case, the currently
performed conversion is cancelled, because its source arbitration level of ‘L2’ is below
the source arbitration level of ‘L1’ of “Channel Injection” A new conversion request is
generated for the cancelled conversion in order to restart this cancelled conversion later.
This new request participates in arbitration and will be selected for repetition due to its
priority level. The second injection request with a source arbitration level of ‘L4’ is
delayed, even if the Cancel-Inject-Repeat feature is enabled.
