Answer 1. If the LCD has be selected to be turned off when the device enters the power down mode, then the LVR/LVD will also be disabled. 2. When the LVR/LVD is enabled, the V1, V2, C1 and C2 pins must be connected to capacitors, otherwise the LVR/LVD function will not run normally. As the LVD/LVR function in this device is supplied by the LCD charge pump, therefore it is necessary to connect the charge pump capacitors.
