Hi guys,

I have a question regarding the Hi-z state of micro controller pins.

My question is can i make my port pin to behave as HIGH, LOW and Inactive.

means i want my port to behave high for some clock cycles, and low for some clock cycles and also Inactive for some clock cycles?

    To go hi-Z, switch the pin to an input (PxDIR bit=0). The PxOUT setting is retained for whenever you turn it back to an output (PxDIR bit=1).

    [Edit: Also, stay away from the PxREN register, which will switch the pin from hi-Z to medium-Z.]
