RF interface

The AD6522 control RF parts through TXEN, RXON1, RXON2, AGCEN, PLL_DATA, PLL_CLK,
PLL_LE etc.

LCD module interface

Mainly controlled by _LCD_MAIN_CS, LCD_RES, LCD_RS, _WR, DATA [00...15] signals.

Description

_LCD_MAIN_CS

LCD driver chip enable. LCD driver IC has own CS pin

LCD_RES

This pin resets LCD module.

LCD_RS (ADD1)

This pin determines whether the data to LCD module are display data or
control data. ADD1 can select 16 bit parallel bus. ADD1 is also used to
address flash memory.

__WR

Write control. The phone do not read data from LCD chip.

DATA [00...15]

Parallel data lines. Color LCD driver chip uses the 16-bit data interface.

3V0_VLCD

Regulated 3V voltage is supplied to white colored LED driver for backlighting.

LCD_BACKLIGHT

_CTL

Control signal of white LED driver IC.
