Can you explain what the difference in behavior is? There's no way to answer your question otherwise.

Thank you for your reply, basically this is a SPI Master State machine

In case when it works fine, it transmits 4 bytes of data continuously after a given delay

After porting it on the 5M570ZT100A5N the behavior becomes unpredictable, it sometimes transmits 2 bytes and stops for ever, sometimes it transmits 3 bytes and stops for ever, sometimes it transmits well for a duration of say 30 seconds and then stops.

I have no clue about the issue right know.
