Activation Sequence
After Power on Reset, the signal
INT is low until the V
DD is stable. When VDD has been stable for
approximately 10 ms and the signal
INT is high, the system controller may read the status register to see
if the card is present. If all the status bits are satisfied, the system controller can initiate the activation
sequence by writing a '1' to the Start/Stop bit (bit 0) of the control register.
The following steps and Figure 8 show the activation sequence and the timing of the card control signals
when the system controller initiates the Start/Stop bit (bit 0) of the control register:
1.
Voltage VCC to the card should be valid by the end of t1. If VCC is not valid for any reason, then
the session is aborted.
2.
Turn I/O to reception mode at the end of t1.
3.
CLK is applied to the card at the end of t2.
4.
RST (to the card) is set high at the end of t3.

Deactivation Sequence
Deactivation is initiated either by the system controller by resetting the Start/Stop bit, or automatically in
the event of hardware faults. Hardware faults are over-current, over-temperature, VDD fault, VPC fault, VCC
fault, and card extraction during the session.
The following steps and Figure 9 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.
