6.16.4. Color LCD Power supply function
Power supply of color LCD unit is controlled by LCDPWR port.
6.16.5. Color LCD communication function (USB interface)
• USB 2.0 High -Speed (Transfer rate 480Mbps)
After MFP is turned ON, USBH0_PWR goes to "H" when MAIN BOAD is ready to communicate, and then +5V is supplied to the
USB MEMORY from IC405. And IC7 controls USB devices (IC2 and USB MEMORY).
