The Vernier Control Register provides the delay line tap control when using the vernier option.
VERNIER[7:0]
The vernier tap register bits VERNIER[7:0] specifies the phase delay through the DLL when
using the vernier feature. When VERN_EN is set high, the VERNIER[7:0] registers specify
the delay tap used. When VERN_EN is set low, the VERNIER[7:0] register is ignored. A
VERNIER[7:0] value of all zeros specifies the delay tap with the minimum delay through the
delay line. A VERNIER[7:0] value of all ones specifies the delay tap with the maximum
delay through the delay line.
