The following sequence corresponds with the numbered items in
1. The local read request signal is asserted.
2. The controller accepts the request, the local_ready signal is asserted.
3. The controller asserts the ctl_doing_rd to tell the PHY how many clock cycles of
4. The read command (RD) on the command bus.
5. The mem_dqs signal has the read data from the controller.
6. These are the data to the controller with the valid signal.
7. The controller returns the valid read data to the user logic by asserting the
read data to expect.
local_rdata_valid signal when there is valid local read data.
