LogiCORE SPI-4.2 (POS-PHY L4) v7.2 - SPI-4.2 v7.x Source core does not send data when DataMaxT < 8


General Description: 

When I set the static configuration signal DataMaxT or the GUI option "Number of Data Cycles before Training" to 1 to 8, the Source Core sends periodic training patterns after going in frame instead of sending data or idles. If DataMaxT = 0, this problem does not occur, and the core never sends periodic training patterns.


This core issue occurs when "Number of Data Cycles before Training" is set to 1 to 8. If possible, set "Number of Data Cycles before Training" to a value greater than 8, and the core will function correctly.
