ECC Data Mask: DM is an optional output mask signal
for write data. Output data is masked when DM is
sampled HIGH coincident with that output data during a
Write access. DM is sampled on both edges of ECC_DQS.
This signal is muxed with channel 1 and may not be
needed.

ECC Data Strobes: The data is captured at the crossing
point the ‘P’ and its compliment ‘N’ during read and write
transactions. For reads, the strobe crossover and data
are edge aligned, whereas in the Write command, the
strobe crossing is in the centre of the data window.
