Description
This demo example shows the operating of LCD Extension board.

From the main.c source file:

Initialization
1     SystemInit();
2     CGU_Init();
Init SysTick to 1ms
1     SysTick_Config(CGU_GetPCLKFrequency(CGU_PERIPHERAL_M4CORE) / 1000);
Configure external flash
1     MemoryPinInit();
2     EMCFlashInit();
Init LCD
1     LTV350QV_Init(intro);
Enable backligth
1     scu_pinmux(0x9, 5, MD_PLN, FUNC4);  // P9_5 = GPIO5[18]
2     GPIO_SetDir(5, (1 << 18), 1);
3     GPIO_SetValue(5, (1 << 18));
Init touch controller
1     TSC2007_Init();
