Field
31–26
Horizontal sync pulse width. Specifies the number of LCD_LSCLK periods that LCD_HSYNC is activated. The
H_WIDTH
active time is equal to (H_WIDTH + 1) of the LCD_LSCLK periods.
25–16
Reserved, must be cleared.
15–8
Wait between LCD_OE and LCD_HSYNC. In TFT mode, this field specifies the number of LCD_LSCLK periods
H_WAIT_1
between the end of LCD_OE signal and the beginning of the LCD_HSYNC. Total delay time equals
(H_WAIT_1 + 1) of LCD_LSCLK periods.
In CSTN mode, H_WAIT_1 specifies the number of LCD_LSCLK periods between the last display data and the
beginning of the LCD_HSYNC signal. Total delay time equals (H_WAIT_1 + 1) of LCD_LSCLK periods.
7–0
Wait between LCD_HSYNC and start of next line. In TFT mode, this field specifies the number of LCD_LSCLK
H_WAIT_2
periods between the end of LCD_HSYNC and the beginning of the LCD_OE signal. Total delay time equals
(H_WAIT_2 + 3).
In CSTN mode, H_WAIT_2 specifies the number of LCD_LSCLK periods between the end of LCD_HSYNC and
the first display data in each line. Total delay time equals (H_WAIT_2 + 2) of LCD_LSCLK periods.

LCDC Vertical Configuration Register (LCD_VCR)
The vertical configuration register defines the vertical sync pulse timing. For detailed settings, please refer
to the panel's data sheet.
