Power Down Sequence
Power down sequence for SIM interface is as follows:
1. SIMPD port detects the removal of the SIM Card
2. RST goes Low
3. CLK goes Low
4. TX goes Low
5. VEN goes Low
Each of this steps is done in one CKIL period (usually 32 kHz). Power down can be started because of a
SIM Card removal detection or launched by the processor. Figure 76 and Table 58 show the usual timing
requirements for this sequence, with Fckil = CKIL frequency value.
