The reset signal is also used as the counting signal of the sub-counter, and the sub-counter will be increased by 1 for every full 60 seconds. When the counter is full 24, the Q0-Q3 of the ten bits will be 0010 and that of the individual bits will be 0100, which will be connected to the counter after Q2 is done with the algorithm, so that the counter can be reset from 6 to 0 in advance.
