Reserve Pin logic option

A logic option that reserves the pin in one of the following seven states:

  • as an input that is tri-stated
  • as an output that drives ground
  • as an output that drives VCC
  • as an output that drives an unspecified signal
  • as a Signal Probe output
  • as a voltage reference (VREF)
  • as a bidirectional pin
Note:

The "as VREF" setting is not appropriate for all device families. Refer to the device family data sheet for information on VREF support.
