pullup resistors set on high

[group9]

hello
i have one input (to my device acting like a chip select wich can be any general I/O )that has an internal pull-up resistor and
should be left open (tri-stated by the microcontroller). i don't know how this is done.the pin in question is an output to my micrcontroller.

PIN X :Input with internal pullup resistor (input to device)
Should be driven high or high-impedance to minimize
power consumption

if anyone has an idea onhow this done this could be a great help
thank

If you set a pin as an input (just read from it, if you are using 'standard_io', or change the tris), then the ouput drivers in the PIC are turned off. The instruction 'output_float', also does the same thing, without you having to read the pin.
