selected. If TDIRB = 0, downward counting is
selected. (

Analog supply voltage for ADC (3.3 V)§
VSSA

84
22
Analog ground reference for ADC
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.
