†
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.
