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]
