As shown in Figure 2, producing period t1 step is:
A1 begins;
A2 judges whether in this way, to enter a3 to the unit timing time, as no, enters a6;
The timing that adds up of a3 cycle count unit, unit timing time of every mistake adds 1 automatically to t1, enters a4;
A4 judges whether t1 〉=n, in this way, enters a5, as no, enters a6;
A5 period t1 value resets;
