[Ronja] How distinguish packets at U63 in Twister?

[Cecilia Puon]

Hello, everybody, I still dont understand how can i send data if the
packets produce zero on U63-10, in agreement with "How does ronja
work?". How can I distinguish the data at the end of U63?

I re-write the part in which Ronja people describes the function of the
pulse extenders, in this part they describe how packets generate zero at
the end of U63.

"U54 is just a buffer. C66 and R52 replace leading edges in the signal
with short H impulses and everything else with L. U52 inverts it and on
every leading edge of the original signal, U63 gets reset to zeroes on
all outputs. On every tick of the 16MHz clock (62.5 ns) one tap gets set
to one. That means if the output is on the 5th tap, it gets set from

0 back to 1 after 4-5 ticks, that means after 250-312.5 ns it gets back to H.

If the incoming signal has the leading edge pitch less than 250ns, then the output stays
permanently in 0. If it has more, then it will contain ones interspersed with zeroes.

The Manchester signal has maximum leading edge pitch of 200ns(5Mhz). The silence between
the packets takes at least 9600ns. So packets will produce zero on U63-10 and the interframe gaps one."

Thank you for your help.
