F21 Network Coprocessor

[Dave Lowry <lowry@xxxxxxxxxxxxxxxxx>]

Thanks, Jeff, for your reply!  But, I'm still confused :-(

The model I have in my head resembles regular asynchronous serial
reception.  That is, after the start bit edge, we count 1/2 bit time
to get into the center of the bit and then do a sample, then count out
full bit times and do samples in the center of the remaining bits.

I'm guessing that's the purpose of the counter, to get centered in a
bit to get a clean sample.  Maybe I'm not understanding the encoding
scheme.  Could you give an example of a waveform for a short bit
sequence?
