Please enter into debug mode for hardware test:

The DEBUG pin allows the product to enter debug mode. To activate the debug mode, voltage applied to the DEBUG pin must be within the VDEBUG_IL and VDEBUG_IH range at start-up. If the voltage applied to DEBUG pin is out of these limits, during the SELECT pin configuration, the device settles into normal mode.
