*										DESCRIPTION
*
* This module provides an interface to JHD12864J Graphical LCD module of size 128x64 dots
* Display controller chip is KS0107/8
* LCD pinout function summarized as below
* --------- LCD		MCU -----------------
* pin 1		Vss 	- 0V
* pin 2 	Vdd 	- 5.0V
* pin 3		Vo  	- LCD Drive Voltage (adjust contrast, trimmer to Vee in our case)
* pin 4		D/I		- LCD_DI (H:Data, L:Command (data or command control))
* pin 5		R/W 	- LCD_RW (H:Read, L:Write (read status or write data/command))
* pin 6		E   	- LCD_EN (H/H->L (IC Select or chip enable, H->L effective))
* pin 7:14	DB0:DB7	- LCD_DATA
* pin 15	CS1		- LCD_CS1 (left, high effective)
* pin 16	CS2		- LCD_CS2 (right, high effective)
* pin 17	RST		- LCD_RST (reset pin, low effective)
* pin 18	Vee		- -10.0V, LCD driving voltage. There is a Vee generator built-in LCD
*					  module, thus there is no need to use external generator IC
* pin 19	EL1 / A - LCD_BL (Depends on the backlight option.
*						If it's a LED backlight, it's an anode.
*					  	If it is EL type, this is EL controller input)
* pin 20	EL2 / K	- GND (Cathode for LED-backlight. EL input (OR NC) for EL-backlight model)
