8.7 Deactivation sequence
When the session is completed, the microcontroller resets bit START at t
10
. The circuit
then executes an automatic deactivation sequence (see Figure 19
):
1. The card is reset by signal RST = low (t
11
).
2. Clock pulse CLK is stopped (t
12
).
3. Pins I/O, C4x and C8x fall to 0 V (t
13
).
4. Pin V
CC
falls to 0 V with typical 0.17 V/µs slew rate (t
14
).
5. The step-up converter is stopped (t
15
) and pins CLK, RST, V
CC
and I/O become low
impedance to ground, if both cards are inactive.
Thus:
