You can observe the output signals from the Convolutional Deinterleaver
by setting the OS[2:0] bits to 0b011.
output waveforms. Signals prefixed by “DI_” are driven on the pin
indicated in parenthesis below the signal name.
The L64704 uses the FSTARTOUT, CO[7:0], and DVALIDOUT signals to
carry the corresponding Deinterleaver outputs.
