The LCD enable (LcdEn) bit is used to enable and disable all LCD controller operation. When LcdEn=0 the LCD controller is disabled. When LcdEn=1, the LCD controller is enabled.
All other control registers should be initialized before setting LcdEn.
The user may program LcdControl last, and configure all eight bit-fields at the same time via a word write to the register. If the user clears LcdEn while the LCD controller is enabled, it is permitted to complete transmission of the current frame before being disabled. Completion of the current frame is signalled by the DMA when it sets the Frame Done (Done) within the LCD status register, which generates an interrupt request.
