Abstract: In at least one embodiment of the invention, an apparatus includes an integrated circuit, which includes a first oscillator terminal and an oscillator discrimination circuit. The oscillator discrimination circuit is operative to generate an indicator of a capacitance value of a load capacitance external to the integrated circuit and coupled to one of the first and second oscillator terminals. The indicator is generated according to a charge time of a reference node coupled to a reference capacitor and a charge time of a node coupled to the first oscillator terminal. The node and the reference node are charged using substantially matched currents.

Abstract: An output pad control logic comprises an output buffer including a plurality of transistors connected to drive signals for an output pad. Each of the plurality of transistors includes an n-well. An n-well generator connects a first voltage to the n-wells of the plurality of transistors of the output buffer in a first mode of operation when a system rail voltage exceeds a pad voltage applied to the output pad. The n-well generator connects the pad voltage to the n-wells of the plurality of transistors of the output buffer in a second mode of operation when the pad voltage applied to the output buffer exceeds the system rail voltage. A switching circuit is responsive to at least one control signal to connect the system rail voltage as the first voltage when the output pad is not driving an LCD display and to connect a larger of the system rail voltage and an LCD drive voltage as the first voltage when the output pad is driving the LCD display.
