D2 Course Delay. Number of 2.5 ns clock periods to count.

Undefined

When this count is completed, the vernier delay (defined by the D2 vernier value programmed

into the waveform D2 vernier delay and action register) is added to the D2 course delay to

place an edge in time

Waveform D2 vernier delay and action must be written immediately before this register for the

waveform memory to be correctly written.
