SIM Power up/down
The SIM power up/down sequence is generated in the UEMEK. This means that the UEMEK generates the reset
switch (RST) signal to the SIM. In addition, the SIMCardDet signal is connected to UEMEK. The card detection is
taken from the SIMCarDet signal, which also detects the removal of the battery. A comparator inside UEMEK does
the monitoring of the SIMCarDet signal. The comparator outputs do not alter state as long as the battery is
connected.
The SIM interface is powered up when the SIMCardDet signal indicates “card in”.
