8.7 Activation sequence
The following device activation sequence is applied when using an external clock; see
1. Pin CMDVCCN is pulled LOW (t0).
2. The internal oscillator is triggered (t0).
3. The internal oscillator changes to high frequency (t1).
4. VCC rises from either 0 V to 3 V or 0 V to 5 V on a controlled slope (t2).
5. Pins I/OUC, AUX1UC and AUX2UC are driven HIGH (t3).
6. The clock on pin CLK is applied to the C3 contact (t4).
7. Pin RST is enabled (t5).
Calculation of the time delays is as follows:
t1 = t0 + 384 1fosc(int)low
t2 = t1
t3 = t1 + 17T / 2
t4 = driven by host controller; > t3 and < t5
t5 = t1 + 23T / 2
Remark: The value of period T is 64 times the period interval of the internal oscillator at
high frequency (1
fosc(int)high); t3 is called td(start) and t5 is called td(end).
