8.8 Deactivation sequence
When a session ends, the microcontroller sets pin CMDVCCN HIGH. The TDA8034HN
then executes an automatic deactivation sequence by counting the sequencer back to the
inactive state (see
Calculation of the time delays is as follows:
1. Pin RST is pulled LOW (t11).
2. The clock is stopped, pin CLK is LOW (t12).
3. Pins I/OUC, AUX1UC and AUX2UC are pulled LOW (t13).
4. V
5. V
6. All card contacts become low-impedance to GND. However, pins I/OUC, AUX1UC
7. The internal oscillator returns to its low frequency mode.
