D. SIM interface
The AD6527B provides SIM Interface Module. The AD6527 checks status periodically during
established call mode whether SIM card is inserted or not, but it doesn't check during deep Sleep
mode. In order to communicate with SIM card, 3 signals SIM_DATA, SIM_CLK,
SIM_RST(GPIO_23) are required. The descriptions about the signals are given by bellow Table 3-6
in detail.
E. Key interface
Include 5 column, 5 row. The AD6527B detects whether key is pressed or not by using interrupt
method.
F. AD6535 Interrupt
AD6535 provides an active-high interrupt output signal. Interrupt signals are generated by the
Auxiliary ADC, audio, and charger modules.
