It's not in the help file, but I can calculate it.
I get 4146 for the BS2p and 6646 for the BS2px.
But will these values actually produce 600 baud ?

No, the baud rate value calculated must fit into 12 bits (0 - 4095).

Drat... Double Drat.
Seems my video overlay project will only work reliably up to 600 baud.
I guess some more work is in order...

If you're looking to make a consumer product, you really should get it up to 2400 baud -- somewhat of a standard with things like that.

Jon, thanks for the push. After 4 hours of work I finally got 2400 baud to work.
@#$#% half-cycle vsync pulses screwed everything up.
But it will be a better design in the long run.
See I may be stubborn...But I do learn...;)
