Check whether the specified LCD flag is set or not.

Parameters:

__HANDLE__	specifies the LCD Handle.
__FLAG__	specifies the flag to check. This parameter can be one of the following values: 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.

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.
LCD_FLAG_UDR: Update Display Request flag.
LCD_FLAG_UDD: Update Display Done flag.
LCD_FLAG_RDY: Step_up converter Ready flag. It indicates the status of the step-up converter.
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.

Return values:

The	new state of __FLAG__ (TRUE or FALSE).
