† _{Bold, italicized pin names indicate pin function after reset.}
‡ _{GPIO − General-purpose input/output pin. 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.)
