Figure 21. Non-TFT Mode Panel Timing
5.11 USB On-The-Go Specifications
The MCF5227x device is compliant with industry standard USB 2.0 specification.
Table 22. Non-TFT Mode Panel Timing
Num Characteristic Min Value Unit
T1 LCD_HSYNC to LCD_VSYNC delay 2 HWAIT2 + 2 Tpix
T2 LCD_HSYNC pulse width 1 HWIDTH + 1 Tpix
T3 LCD_VSYNC to LCD_LSCLK — 0 ≤ T3 ≤ Ts —
T4 LCD_LSCLK to LCD_HSYNC 1 HWAIT1 + 1 Tpix
Note: Ts is the LCD_LSCLK period while Tpix is the pixel clock period. LCD_VSYNC, LCD_HSYNC, and
LCD_LSCLK can be programmed as active high or active low. In Figure 21, all these 3 signals are active
high. When it is in CSTN mode or monochrome mode with bus width = 1, T3 = Tpix = Ts. When it is in
monochrome mode with bus width = 2, 4 and 8, T3 = 1, 2 and 4 Tpix respectively.
