When both VBUS and VBAT exist, setting EN_LEARN=1b to enable mode to allow device to shut off converter and discharge battery to support the system. In this way it can calibrates the battery gas gauge over a complete discharge/charge cycle. When the battery voltage is below battery depletion threshold, the EC host will set EN_LEARN bit back to 0b to switch the device back in forward mode. When device is under learn mode if CELL_BATPRES pin is pulled lower than VCELL_BATPRES_FALL for 1ms deglitch time, then device exits LEARN mode and reset EN_LEARN bit is set back to 0 automatically.
