Abstract
In an embodiment, an apparatus includes an input/output (I/O) buffer to couple a logic unit to another device coupled via a pad, and a logic coupled to the I/O buffer to detect a value on the pad and to control the I/O buffer to provide the value to the pad, responsive to entry into an architectural state. Other embodiments are described and claimed.
Claims20
An apparatus comprising:
- an input/output (I/O) buffer;
- a pad;
- and
- a control circuit to:
- determine a particular configuration of a plurality of configurations associated with the pad, the plurality of configurations comprising a plurality of architectural states and a plurality of directions, the plurality of architectural states comprising at least a reset de-assertion state and a power-good assertion state, and the plurality of directions comprising a transmit direction and a receive direction;
- sample a state on the pad associated with the particular configuration of the pad;
- and
- control the I/O buffer to maintain the sampled state at the pad while the pad is in the particular configuration.

A processor formed in an integrated circuit (IC), the processor including:
- at least one processing engine to execute instructions;
- a pad;
- an input/output (I/O) buffer;
- and
- a controller to:
- determine a particular configuration of a plurality of configurations associated with the pad, the plurality of configurations comprising a plurality of architectural states and a plurality of directions, the plurality of architectural states comprising at least a reset de-assertion state and a power-good assertion state, and the plurality of directions comprising a transmit direction and a receive direction;
- sample a state on the pad associated with the particular configuration of the pad;
- and
- control the I/O buffer to maintain the sampled state at the pad while the pad is in the particular configuration.
