NOTE
1.
The "Turn-ON" delay is defined as the time difference between a transition
of state at the input that turns ON the opto-coupler and the subsequent
transition in the FPGA.
2.
The "Turn-OFF" delay is defined as the time difference between a
transition of state at the input that turns OFF the opto-coupler and the
subsequent transition in the FPGA.
These delays include the delay introduced by the digital line filter controlled
by the
