* @arg LCD_FLAG_ENS: LCD Enabled flag. It indicates the LCD controller status.
* @note The ENS bit is set immediately when the LCDEN bit in the LCD_CR
* goes from 0 to 1. On deactivation it reflects the real status of
* LCD so it becomes 0 at the end of the last displayed frame.
* @arg LCD_FLAG_SOF: Start of Frame flag. This flag is set by hardware at
* the beginning of a new frame, at the same time as the display data is
* updated.
* @arg LCD_FLAG_UDR: Update Display Request flag.
* @arg LCD_FLAG_UDD: Update Display Done flag.
* @arg LCD_FLAG_RDY: Step_up converter Ready flag. It indicates the status
* of the step-up converter.
* @arg LCD_FLAG_FCRSF: LCD Frame Control Register Synchronization Flag.
* This flag is set by hardware each time the LCD_FCR register is updated
* in the LCDCLK domain.
* @retval The new state of __FLAG__ (TRUE or FALSE).
