Post by thread:Tristate a Port?

Hey all, The EASY PIC'N book says that the TRIS instruction "transfers the contents of the W register into the TRIS register which selects port data direction. Is that all that the TRIS instruction does is determine data direction or Can the TRIS instruction actually tristate the port? I mean can it make the port have theoretically infinite resistance to whatever it may be connected to? Sometimes I want to sink current, other times I would like to source and then there are times I want it to act as if it were disconnected from the rest of the circuit, any advise on if this is possible and how I could do that? Thanks, Ken Dougal spam_OUTslm5gTakeThisOuTcc.usu.edu
