Procedure for SAMG55 chiperase:
1) Place jumper in ERASE header
2) Power off the board
3) Power on the board
4) Remove jumper
The ERASE pin has an internal pull-down if
not configured as GPIO in the user application.
Procedure for SAMG55 programming:
1) Power off the board
2) Place jumper in PROG header
3) Power on the board
4) Remove jumper after programming
The PROG pin has an internal pull-up if
not configured as GPIO in the user application.

PA11 can be used to check if power is
available on the target USB.
In case to sense VDC
voltage, select the right
value of the resistor, R14,
according to your voltage
value. And remove
resistor, R15.
