18F4620 Sink Only Output
Is there a subroutine that only sinks an output? I am using an 18F4620 at 5V. The device I am controlling has an input that has a 3.3V pull up. I would like to pull down the 18F4620 output to 0V and then let it go open to 3.3V.

Port Pin Output Tricks
I found a good write-up in digital-diy by Jon Chandler, "Port Pin Output Tricks" that answered my question.
