Caution:
Figure 4-13. Status LEDs.
The LEDs are connected to the pins 9, 10 and 13 of the SAM3S4B microcontroller.
ERASE and VCC pins
The ERASE pin (see Section
(Non-Volatile Memory) bits - to an erased state. The flash is transferred to its original state.
To perform a flash erase operation the pin has to be tied high longer than 220ms while the USB stick is connected to
the PC.
VCC
By electrically connecting the two test points ERASE and VCC the internal MCU flash memory will be deleted. The
firmware as originally available in the board’s delivery condition will be destroyed.
Work carefully, also when handling the board! The moisture of your fingers’ skin may be sufficient under
certain conditions to destroy the internal flash content.
