All GPIOs come up as input after reset. § It is highly recommended that VCCA be isolated from the digital supply voltage (and VSSA from digital ground) to maintain the specified accuracy and improve the noise immunity of the ADC. ¶ Only when all of the following conditions are met: EMU1/OFF is low, TRST is low, and EMU0 is high # No power supply pin (VDD, VDDO, VSS, or VSSO) should be left unconnected. All power supply pins must be connected appropriately for proper device operation. LEGEND: ↑ − Internal pullup ↓ − Internal pulldown (Typical active pullup/pulldown value is ±16 µA.) |
