SDFM: Spurious Data Acknowledge Event When Data Filter is Configured and Enabled for the First Time

Revisions Affected

B, C

Details

When the SDFM data filter is configured and enabled for the first time, it is possible to get one spurious data acknowledge event (AFx) before the data filter settles to give correct digital data. Subsequent data acknowledge events (AFx)/DMA events occur correctly as per data filter configuration.

Workarounds

Do the following:

Configure and enable the SDFM data filter.
Delay for at least latency of data filter + 5 SD-Cx clock cycles.
Enable SDFM data acknowledge interrupts/DMA events.
