DLYFRMS: Number of frames  
This specifies full frame delay part of the command to data delay.  
0 - 9: Valid delays  
10 - 15: Reserved  
3:0  
ROST  
0h  
DLYFRAC: Fractional delay of command to data  
This specifies fractional frame delay part of the command to data delay.  
0 - 11: Specifies the delay in 1UI increments  
12 - 15: Reserved  
14.3.5.3  
C2DINCRNXT: Next Value of Command to Data Delay Increment  
This register has the next value of the command to data incremental delay. This will be  
used after the next fast reset. This will be used by the last AMB to delay driving the  
data beyond that specified in the command to data delay.
