3. TECHNICAL BRIEF
3.5.1 Interconnection with external devices
A. RTC block interface
Countered by external X-TAL
32.768kHz oscillator supplies on-chip Real Time Clock circuitry
B. LCD module interface
The LCD module is controlled via mobile media processor AIT716
If AIT716 is in the state of by-pass mode, the LCD control signals from AD6726
are by-passed through AIT716.
In operating mode, the AIT716 controls the LCD module through nLCD_CS, nLCD_RS,
nLCD_WR, L_DATA08~L_DATA15.
Signals Description
nLCD_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 AD6726 directly.
nLCD_WR
Enable writing to LCD Driver.
nLCD_RS
This pin determines whether the data to LCD module are LCD command
or data.
2V8_MM
2.8V is supplied to LCD driver IC.
LCD_ID
Identify LCD module maker
