Reset:
The DLL logic is internally used by the controller in order to delay DQS inputs. This is necessary to center the strobe time
and the data valid window.
• MDINC: DLL Master Delay Increment
0 = The DLL is not incrementing the Master delay counter.
1 = The DLL is incrementing the Master delay counter.
• MDDEC: DLL Master Delay Decrement
0 = The DLL is not decrementing the Master delay counter.
1 = The DLL is decrementing the Master delay counter.
• MDOVF
0 = The Master delay counter has not reached its maximum value, or the Master is not locked yet.
1 = The Master delay counter has reached its maximum value, the Master delay counter increment is stopped and the DLL
forces the Master lock. If this flag is set, it means the DDRSDRC clock frequency is too low compared to Master delay line
number of elements.
• MDVAL
Value of the Master delay counter.
