1.2.8. PMA Reconfiguration

Modifying programmable values within transceiver buffers can be performed by a single reconfiguration controller for the entire FPGA, or multiple reconfiguration controllers if desired. Within each transceiver bank a maximum of two reconfiguration controllers is allowed; one for the three channels (triplet) in the upper-half of a bank, and one for the lower-half. This is due to a single Avalon-Memory Mapped (AVMM) slave interface per triplet Therefore, many triplets can be connected to a single reconfiguration controller, but only one reconfiguration controller can be connected to the three transceivers within any triplet.
