Hi all,

Anyone try and use the Comm inverting feature that is on chips like an 18F2540?
The register is BAUDCON and bit RXDTP sets RX polarity. I don't know how many chips it is available on, but I have found a few.

I would like to be able to make a selectable "invert" on non-RXDTP chips, but so far, I haven't come up with an elegant way. Trying a couple of transistors in a totem pole, but not exactly working yet.

Just fishing for ideas.

Mark
