Notes to Figure 7:
1. Reset.
2. An input clock is selected.
3. The T0 selected input clock is disqualified AND No qualified input clock is available.
4. The T0 selected input clock is switched to another one.
5. The T0 selected input clock is locked (the T0_DPLL_LOCK bit is ‘1’).
6. The T0 selected input clock is disqualified AND No qualified input clock is available.
7. The T0 selected input clock is unlocked (the T0_DPLL_LOCK bit is ‘0’).
8. The T0 selected input clock is locked again (the T0_DPLL_LOCK bit is ‘1’).
9. The T0 selected input clock is switched to another one.
10. The T0 selected input clock is locked (the T0_DPLL_LOCK bit is ‘1’).
11. The T0 selected input clock is disqualified AND No qualified input clock is available.
12. The T0 selected input clock is switched to another one.
13. The T0 selected input clock is disqualified AND No qualified input clock is available.
14. An input clock is selected.
15. The T0 selected input clock is switched to another one.
The causes of Item 4, 9, 12, 15 - ‘the T0 selected input clock is
switched to another one’ - are: (The T0 selected input clock is disquali-
fied AND Another input clock is switched to) OR (In Revertive switch, a
qualified input clock with a higher priority is switched to) OR (The T0
selected input clock is switched to another one by External Fast selec-
tion or Forced selection).
T0 input clock qualification.
