Claim:
1. An input/output (IO) pad circuitry of an integrated circuit (IC), the IO pad circuitry comprising: an IO pad circuit configured to receive and transmit at least a signal respective of the IC; monitoring circuitry connected to the IO pad circuit configured to perform error detection of both a received signal of the IO pad circuit and a transmitted signal of the IO pad circuit; and correction circuitry connected to the IO pad circuit configured to override a signal value with a predetermined safe value respective of a predetermined safety mode to ensure that signals provided to and from the IO pad behave correctly such that signals propagated into and out of the IC via the IO pad circuit do not disrupt the operation of the IC and the other components of the system externally connected to the IO pad circuit.
