Abstract
Techniques and circuits for ensuring undefined control signals are not inadvertently driven onto a bus due to core logic and I/O logic supply voltages reaching final voltage levels at different times are provided. According to some embodiments, an internal voltage supply sense circuit may monitor a level of a voltage supply that powers core logic that generates control signals to be driven on I/O pads. The sense circuit may generate one or more control signals used to keep I/O pads in a high impedance state.
