Reports the lock status and the encoder value for data slice 0. READ-ONLY
There is a separate dll_obs_reg_0_X parameter for each of the slices of data sent on the DFI data bus.
Bits [31:1] = Reports the DLL encoder value from the master DLL to the slave DLL's. The slaves use this
value to set up their delays for the clk_wr and read DQS signals.
Bit [0] = DLL Lock Indicator.
'b0 = DLL has not locked.
'b1 = DLL is locked.
