Sip communication

[amarsoma05]

We are making rt1170 as a master and pn7462 as a slave and used spi communication .

Master data send to slave is successfully . From slave to master data sending is happening but 1st four bytes of information is missing 

We checked with logic anlyzer ...

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I was wondering if you can illustrate the expected SPI transfer signal.
Hope it helps.
Have a great day,
TIC
