3. TECHNICAL BRIEF

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, CL761S If CL761S is in the state of by-pass mode, the LCD
control signals from AD6527 are by-passed through CL761S.
In operating mode, the CL761S 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_VEXT, IF_MODE, LCD_ID[0:2].

Signals Description
