3. TECHNICAL BRIEF
- 24 -
3.5.1 Interconnection with external devices
A. RTC block interface
Countered by external X-TAL
The X-TAL oscillates 32.768KHz
B. LCD module interface
The LCD module is controlled by CAMERA IC, CL765A
If CL765A is in the state of by-pass mode, the LCD control signals from AD6527 are by-passed
through CL765A.
In operating mode, the CL765A controls the LCD module through L_MAIN_LCD_CS,
L_SUB_LCD_CS, LCD_RESET, LCD_RS, LCD_WR, LCD_RD, L_DATA[15-00], 2V8_MV,1.8_MV.
Signals
Description
L_MAIN_LCD_CS
MAIN LCD driver chip enable. MAIN LCD driver IC has own CS pin
L_SUB_LCD_CS
SUB LCD driver chip enable. SUB LCD driver IC has own CS pin
LCD_RESET (GPIO 15)
This pin resets LCD module. This signal comes from DBB directly.
LCD_WR
Enable writing to LCD Driver.
LCD_RD
Enable reading to LCD Driver.
LCD_RS
This pin determines whether the data to LCD module are display
data or control data. LCD_RS can select 16 bit parallel bus.
2V8_MV,1V8_MV
2.85V voltage is supplied to LCD driver IC.
LCD_SIGNAL1
(GPIO_16)
For the future.
LCD_SIGNAL2
(GPIO_17)
