Advisory

SDFM: Dynamically Changing Data Filter Settings (Such as Filter Type or DOSR) Will Trigger Spurious Data Acknowledge Events

Revisions Affected

B, C

Details

When SDFM data settings—such as filter type or DOSR settings—are dynamically changed during run time, spurious data-filter-ready events will be triggered. The spurious data-ready event will trigger a corresponding CPU interrupt, CLA task, and DMA trigger if configured appropriately.

Workarounds

When SDFM data filter settings need to be changed dynamically, follow the procedure below to ensure spurious data-filter-ready events are not generated:

Disable the SDFM data filter.
Change SDFM data filter settings such as filter type or DOSR.
Delay for at least a latency of data filter + 5 SD-Cx clock cycles.
Enable the SDFM data filter.
