Bit 6 – CMEN Color Mode Signal Enable

Value	Description
0	No effect.
1	Sets the color mode signal (lcd_cm) to one. If a rising edge is generated, signals the MIPI DSI host to send a “Color Mode On” command to the LCD screen when the MIPI output interface is selected.

Bit 5 – SDEN Shutdown Signal Enable

Value	Description
0	No effect.
1	Sets the shutdown signal (lcd_sd) to zero (turns on the display).

Bit 3 – PWMEN LCDC Pulse Width Modulation Enable

Value	Description
0	No effect.
1	PWM is enabled.

Bit 2 – DISPEN LCDC DISP Signal Enable

Value	Description
0	No effect.
1	LCDC_DISP signal is generated.

Bit 1 – SYNCEN LCDC Horizontal and Vertical Synchronization Enable

Value	Description
0	No effect.
1	Both horizontal and vertical synchronization (LCD_VSYNC and LCD_HSYNC) signals are generated.

Bit 0 – CLKEN LCDC Pixel Clock Enable

Value	Description
0	No effect.
1	Pixel clock logical unit is activated.
