3. TECHNICAL BRIEF
D. SIM interface
The AD6522 check status periodically in call mode if SIM card is inserted or not , but the AD6522
don't check in deep sleep mode.
Interface by SIM_IO, SIM_CLK, SIM_RST
SIM_IO
SIM_CLK
SIM_RST
E. Key interface
Include 5 column and 5 row.
The AD6522 detect key press by interrupt.
F. AD3408 interrupt
There are two interrupts EOC and CHARGERDETECT
EOC: End Of Charge. Charging would be stopped when AD6522 receive this interrupt.
CHARGERDETECT: This interrupt is generated when charger is inserted.
