0x0 = no action.

0x1 = drive low.

0x2 = drive high.

0x3 = force off.

0x4 = force on.

0x5 = force down.

0x6 = force up.

0x7 = edge compare low.

0x8 = edge compare high.

0x9 = edge compare off.

0xA = edge compare valid.

0xF = close window/compare unknown.

D1 Course Delay. Number of 2.5 ns clock periods to count.

Undefined

When this count is completed, add the vernier delay (defined by the D1 vernier value programmed

into the waveform D1 vernier delay and action register) to the D1 course delay to place an edge in

time.

Waveform D1 vernier delay and action must be written immediately before this register for the

waveform memory to be correctly written.
