The ALTMEMPHY megafunction uses the control_doing_rd signal to enable
its capture registers for the expected duration of the memory burst.

local_rdata_valid signal when there is valid read data on the local_rdata
bus. If Enable error correction and detection logic is disabled, there is no delay
between the control_rdata and the local_rdata buses. If there is ECC logic
in the controller, there is one or three clock cycles of delay between the
control_rdata and local_rdata buses.
