Deactivation sequence
When the session is completed, the microcontroller resets bit START/STOP to logic 0 (t10). The circuit then executes an
automatic deactivation sequence (see Fig.5):
1. Card reset (RST falls LOW) (t11)
2. Clock is stopped (t12)
3. I/O falls to 0 V (t13)
4. V
5. The DC-to-DC converter is stopped (if both cards are inactive) and CLK, RST, V
6. The internal oscillator changes to its low frequency if both cards are inactive (t15).
t11 = t10 + T/64; t12 = t11 + T/2; t13 = t11 + T; t14 = t11 + 3T/2; t15 = t11 + 7T/2.
