TIMER CIRCUIT WITH AUTONOMOUS FLOATING OF PINS AND RELATED SYSTEMS, METHODS, AND DEVICES

Abstract:

An electrical system includes an integrated circuit device including input/output (I/O) pins, a reset circuit, and an I/O circuit. The I/O circuit is operably coupled to the I/O pins. The I/O circuit is configured to selectively operate the I/O pins in an electrically floating state responsive to a system reset signal transmitted by the reset circuit. The I/O circuit is further configured to selectively operate the I/O pins in the electrically floating state responsive to a signal provided by a timer circuit independently from the reset circuit.
