8 Deactivation Sequence
Deactivation is initiated either by the system controller by setting the CMDVCC high, or automatically in
the event of hardware faults. Hardware faults are over-current, overheating, V
and card extraction during the session. To be noted that V
fault is generated when V
The following steps show the deactivation sequence and the timing of the card control signals when the
system controller sets the CMDVCC high or OFF goes low due to a fault or card removal:
