8.7 Activation sequence
The following device activation sequence is applied when using an external clock; see
Figure
Calculation of the time delays is as follows:
Remark: The value of period T is 64 times the period interval of the internal oscillator at
high frequency (
1. Pin CMDVCCN is pulled LOW (t0).
2. The internal oscillator is triggered (t0).
3. The internal oscillator changes to high frequency (t1).
4. V
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).
