OFF and Fault Detection
There are two cases for which the system controller can monitor the
OFF signal: to query regarding the
card presence outside card sessions, or for fault detection during card sessions.
Monitoring Outside a Card Session
In this condition,
CMDVCC is always high, OFF is low if the card is not present, and high if the card is
present. Because it is outside a card session, any fault detection will not act upon the
OFF signal. No
deactivation is required during this time.
Monitoring During a Card Session
CMDVCC is always low, and OFF falls low if the card is extracted or if any fault is detected. At the same
time that
OFF is set low, the sequencer starts the deactivation process.
Figure 6 shows the timing diagram for the
CMDVCC, PRES, and OFF signals during a card session and
outside the card session.
