FXLS9xxx SPI Error due to Asynchronous Timing Discard

[mpierpaolo1]

Hi,

We are facing an issue, 
implementing an initialization procedure as described in the example in the paragraph "13.4 Example SPI command list" in the NXP application:
"AN12386 SPI Communication Procedure Recommendations for the FXLS9xxxx
Rev. 1.2 — 8 January 2021 Application note"

In detail We receive an error after every attempt of Reading
DEVSTAT and COUNT Register
with Command = 0xC00000D1 

The FXLS response is always 
0x0C0003D4 for each 
Read DEVSTAT and COUNT Register Command = 0xC00000D1 
This means " SPI Error due to Asynchronous Timing Discard" as said in Figure 5 Flow-Chart

We checked SPI: signal integrity and timing all seems OK;
Command seems OK (MSB-first 32 bits) and the FXLS response has CRC correct so 
We are wondering if someone else already faced this issue in the past 
to receive some tips

Thanks and Regards
piero
