F. SIM interface
The AD6527 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.
