SIM Interface

The UEM contains the SIM interface logic level shifting. The SIM supports 3V and 1.8V
SIMs. SIM supply voltage is selected by a register in the UEM. It is only allowed to
change the SIM supply voltage when the SIM IF is initialized.
The SIM power up/down sequence is generated in the UEM. This means that the UEM
generates the RST signal to the SIM. Also the SIMCardDet signal is connected to UEM.
The card detection is taken from the BSI signal, which detects the removal of the battery.
The monitoring of the BSI signal is done by a comparator inside UEM. The comparator
offset is such that the comparator output does not alter state as long as the battery is
connected. The threshold voltage is calculated from the battery size specifications.
The SIM interface is powered up when the SIMCardDet signal indicates "card in". This
signal is derived from the BSI signal.
