3.8 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, 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:
