(2) Interconnection with external devices
A. RTC Block Interface
Countered by external crystal oscillator (MC-146, X100).
The X-tal oscillates 32.768 KHz.
B. LCD Module Interface
Controlled by LCD_CS, LCD_RES, ADD1, WR, DATA[0:15], LCD_DIM, and LCD_ID.
C. RF Interface
The AD6525 control RF parts through RF_EN, ANT_SW1/2, PA_EN, PA_BAND,
PDNB,S_EN, S_DATA, AND S_CLK.
