None of it was described. The controller reaches memory through a pipeline stage with a gate nothing else claims, so it is switched off as unused. The glue registers share a clock with the multiplexer, which probes after the controller has programmed them: unless the controller holds that clock, the writes are lost and the port keeps the bootloader's delays. The multiplexer and the on-chip PHY bus start disabled: a board enables the multiplexer with the controller, and the on-chip bus only when it uses that PHY.
