Deactivation Sequence
Deactivation is initiated either by the system controller resetting the Start/Stop bit, or automatically in the
event of hardware faults. Hardware faults are over-current, over-temperature, VDD fault, VCC fault, and
card extraction during the session.
The following steps and Figure 7 show the deactivation sequence and the timing of the card control
signals when the system controller clears the Start/Stop bit:
1. RST goes low at the end of t1.
2. CLK goes low at the end of t2.
3. I/O goes low at the end of t3. Out of reception mode.
4. Shut down VCC at the end of time t4.

10 Interrupt
The interrupt is an active low interrupt. It is set low if either a VCC fault or a VDD fault is detected. It is also
set low if one of the following status bit conditions is detected:
Early ATR
Mute ATR
Card insert or card extract
Protection status from Over-current or Over-heating
If the interrupt is set low by the detection of these status bits, then the interrupt is set high when these
status bits are read. (READ STATUS DONE)
