ECC is active in the channel (ECC): 
00 =no ECC active in the channel 
01 =ECC is active in IO, ECC logic is not active In 
this case, on write accesses the data driven 
on ECC byte is copied from DQ 7:0 (to be 
used in training or IOSAV) 
10 =ECC is disabled in IO, but ECC logic is 
enabled (to be used in ECC4ANA mode) 
11 =ECC active in both IO and ECC logic
