3.7.4. SIM Interface
SIM interface scheme is shown in (Figure 8).
SIM_IO, SIM_CLK, SIM_RST ports are used to communicate DBB with ABB and the Charge Pump in
ABB enables 1.8V/3V SIM operation.
SIM Interface
SIM_CLK SIM card reference clock
SIM_RST SIM card async/sync reset
SIM_IO SIM card bidirectional data line
SIM_PWCTRL SIM card power activation
SIM_CD SIM card presence detection
