1. Readback of the configuration bit stream when simultaneously writing to a PFU in either SSPM fast mode or SDPM fast mode is not allowed.
2. Because the setup time of data into the latches/FFs is less than 0 ns, data written into the RAM can be loaded into a latch/FF in the same
PFU on the next opposite clock edge (one-half clock period).
Note: Speed grades of -5, -6, and -7 are for OR2TxxA devices only.
