*										DESCRIPTION
*
* This module provides an interface to CM50012ACT6 65k color graphical LCD module of 128x160dots
* Display controller chip is Hyvix HDC1600
* Module requires 3.3V DC supply to Vdd, LED backlight requires 6.2-6.5V, 15mA typical
*
* LCD pinout function summarized as below
* --------- LCD		MCU -----------------
* pin 1		LED-K 	- GND (Cathode for LED-backlight)
* pin 2 	LED+A 	- LED backlight, requires 6.2-6.5V, 15mA typical
* pin 3		Vss  	- GND
* pin 4		Vdd		- 3.3V Supply
* pin 5		n.c.	- shunt to ground
* pin 6		n.c.	
* pin 7		CS		- chip select, low active
* pin 8		RST		- reset, low active; wired to manual reset switch of the whole system
* pin 9		A0		- (H:Data, L:Command (data or command control))
* pin 10	WR		- active low, L:Write; use with RD pin
* pin 11	RD		- active low, L:Read; use with WR pin
* pin 12:19	D7:D0	- LCD_DATA 
* pin 20			- Vss
