/** @file
The third stage of the write training is determining the PI setting for each
byte strobe to make sure that data is sent at the optimal location.
In order to do that a pattern of alternating zeros and ones is written to a block of the memory, and then read out.
By identifying the location where it is farthest away from where errors are shown the DQS will be aligned to the
center of the eye.
