Advisory

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

Revision Affected

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.

Workaround

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 data filter.
Delay for at least a latency of the data filter + 3 SD-Cx clock cycles.
Change data filter settings such as filter type and DOSR.
Delay for at least a latency of the data filter + 5 SD-Cx clock cycles.
Enable the data filter.
