Abstract
Circuits and methods for defining functionality of swappable pins are provided. A power-on-reset (POR) circuit detects that a supply voltage is above a POR threshold during start-up or a reset operation. Transmission gate circuits monitor inputs from a first pin and the second pin and deactivate once the POR circuit detects that the supply voltage is above the POR threshold. A latch circuit receives outputs of the transmission gate circuits as inputs. Once the supply voltage is above the POR threshold, the latch circuit generates a first output corresponding to the first pin, and a second output corresponding to the second pin, where the first pin is defined as a I/O pin and the second pin is defined as a capacitance pin or vice versa based on the first output and the second output.
