3.7 LCD MODULE

Controlled by L_MAIN_LCD_CS, L_SUB_LCD_CS, LCD_RESET, LCD_RS,

LCD_WR,LCD_RD,L_DATA[00:17] ports

• L_MAIN_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.

• LCD_RS: This pin determines whether the data to LCD module are display data or control data.

• L_WR : Write control Signal

• L_RD : Read control Signal. But this pin used only for debugging.

• L_DATA[00:17] : Parallel data lines.

• LCD_SIGNAL1 : LCD type selection signals

• For using 65K color, data buses should be 16 bits.
