Waveform D3 Course Delay

Table 27. Waveform D3 Course Delay
Position
Description
Bits[15:00]
D3 Course Delay. Number of 2.5 ns clock periods to count.
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.
