4.3.20.3 Power Down Sequence
Power down sequence for SIM interface is as follows:
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.
requirements for this sequence, with Fckil = CKIL frequency value.
