LMK04828: SPI read-back

Part Number: LMK04828

Hi,

I'm trying to do a SPI read back through the SDIO pin (I/O).

I do not see expected results. I see the MSB missing on read back. I'm checking on the scope.

Can you send me a timing wave form for read, the one in datasheet is not clear.

Please help.

Thanks,

Shuhood

Hi Mohamed,
Thanks for contacting us. I will send you a snapshot of the readback soon.
Please send us a snapshot of the scope where you see not expected behavior.
Best regards

Thanks.

I understood my setup limitation. No issues with the read.

Anyways, please send the read waveforms.
