Can the rx_st_valid signal get deasserted even though rx_st_ready is still asserted?

Environment

  • PCI Express
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description Yes, the rx_st_valid signal can get deasserted even when rx_st_ready is asserted. This behavior can be more prevalent in 128-bit interfaces when you do multiple Memory Writes (MWr) even though other transactions can lead to this behavior as well.
