> 3.9 | SIM Interface

> The SIM interface is intended for 3V and 1.8V SIM cards. The card holder is a five wire interface according to GSM 11.11. A sixth pin has been added to detect whether or not the SIM card drawer is inserted.
> Figure 10: SIM card holder
> Removing and inserting the SIM card during operation requires the software to be reinitialized. Therefore, after reinserting the SIM card it is necessary to restart TC65 Terminal.
> Note: No guarantee can be given nor any liability accepted, if loss of data is encountered after removing the SIM card during operation.
> Also, no guarantee can be given for properly initializing any SIM card that the user inserts after having removed a SIM card during operation. In this case the TC65 Terminal must be restarted by the application.

> Table 12: | Pin assignment – SIM card holder

> Pin number on holder | Signal name | I/O | Function
> 1 | VSIM | O | Supply voltage for SIM card is generated by the module.
> 2 | CCRST | O | Chip card reset, prompted by the module
> 3 | CCCLK | O | Chip card clock
> 4,8 | GND | - | Ground
> 5 | CCVPP | - | Not connected
> 6 | CCIO | I/O | Serial data line, bi-directional
> 7 | CCIN | I | Chip card drawer detection 0 = Chip card drawer inserted 1 = Chip card drawer not inserted Input on the baseband processor for detecting the chip card drawer in the holder; if the SIM is removed during operation the interface is shut down immediately to prevent destruction of the SIM.
