How pins are to be handled in deep standby mode is indicated below. 

For the states of pins in deep standby mode, refer to the corresponding items under section, 38.1, 
Pin States. Handling of unused pins as described under section 38.2, Treatment of Unused Pins, 
also applies in deep standby mode. 

1.2-V power (Vcc, PLLVcc, 
USBDVcc, USBUVcc, USBAVcc) 

Supply power at 1.2 V  

3.3-V power (PVcc, AVcc, 
USBDPVcc, USBAPVcc) 

Supply power at 3.3 V 

Ground (Vss, PLLVss, USBDVss, 
USBUVss, USBAVss, AVss, 
USBDPVss, USBAPVss) 

Connect to ground 

VBUS 

Fix the level on this pin (pull it up or down, or connect it to 
the power-supply or ground level) or open circuit. However, 
note that current as indicated in table 37.2, DC 
Characteristics (2) [Current Consumption] will be drawn by 
the pin fixed to the high level. 

REFRIN 

Connect this pin to USBAPVss via a 5.6 k

  1 % resistor 

AVref 

Fix the level on this pin (from 3.0 V to AVcc) 

EXTAL, RTC_X1, USB_X1 

Connect the pins to the crystal oscillator or the clock-input 
signal, or to a fixed level (pull them up or down, or connect 
them to the power-supply or ground level) 

XTAL, RTC_X2, USB_X2 

Connect the pins to the crystal oscillator or open circuit 

Dedicated input pins other than 
those listed above 

Fix the level on the pins (pull them up or down, or connect 
them to the power-supply or ground level). 

Input/output pins (other than those 
listed above) in the input state 

Fix the level on the pins (pull them up or down). 

Input/output pins (other than those 
listed above) in the high-impedance 
state 

Fix the level on the pins (pull them up or down) or open 
circuit.
