Bits[15:00] 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.
