D3 Course Delay. Number of 2.5 ns clock periods to count.

Undefined

When this count is completed, the vernier delay (defined by the D3 vernier value programmed into

the waveform D3 vernier delay and action register) is added to the D3 course delay to place an edge

in time.

Waveform D3 vernier delay and action must be written immediately before this register for the

waveform memory to be correctly written.
