The EWCRi06 bit in the EWCRi register (i=0 to 3) determines whether the recovery cycle is added or not.
In the recovery cycle, addresses and wrie data outputs are provided continuously (using the separate bus
only). Devices, which take longer address hold time and data hold time to write data, are connectable.
