Abstract
The invention provides an input/output (I/O) signaling voltage range discriminator (and corresponding method) which is used to control a configurable logic device such as a configurable I/O buffer in a second electronic circuit in response to a detected signaling voltage range of a first electronic circuit. The discriminator outputs an indication of the signaling voltage range of the first electronic circuit to a configurable I/O buffer enabling it to adapt to the signaling levels used by the first electronic circuit. The I/O buffer, based on the indication provided by the discriminator, can then configure its logic to become tolerant and/or compatible with digital signals transferred to and from the first electronic circuit.
