• _LCD_CS : MAIN LCD driver chip enable. MAIN LCD driver IC has own CS pin
• LCD_RESET : This pin resets LCD module. This signal comes from DBB directly.
• ADD01: This pin determines whether the data to LCD module are display data or control data.
• IFMODE : This can select 16bits or 8bits parallel bus. But for the future.
Default is low (low is 16bits interface)
• _WR : Write control Signal
• _RD : Read control Signal. But this pin used only for debugging.
• DATA[00:15] : Parallel data lines.
• LCD_ID[1:2] : LCD type selection signals
- LCD_ID1 : LCD maker(2.4V is SII, 0V is HyeLCD)
- LCD_ID[2:3] : for the future using
• For using 65K color, data buses should be 16 bits.
