delays and other latencies [range = –500000000 to 500000000 ns = ±0.5 s]
Edge : Used to determine if the on-time point of the 1PPS output is the rising or the falling
edge of the signal.
Pulse Width [ns]: Configures the Pulse Width of the 1PPS output.
[range= 20 to 900000000 ns = 0.0s μs to 0.9 s]
[default = 200 ms]
