GPIO Buffer Impedance Compensation

All GPIO buffers require impedance compensation for 1.8 V and 3.3 V operation. The impedance compensation is done via the GPP_​RCOMP signal, which requires a precision pull down resistor of 200 Ohm (1%) to GND. Without proper impedance compensation, the GPIO buffers, including the muxed native functions, may not operate as expected.
