The counter varies an positive-edge clock transation and it can be cleared by the MAS- TER BESET input. The output from this timer is the Q or Q output from the 8th, 13th, or 16th counter stage. The choice of the stage depends on the time- select inputs A or B (see frequency selection table). The output is available in one of the wo modes that can be selected via the MODE input, pin 10 (see truth table}. The output turns out as a continuous square wave, with a tregueney equal to the oscillator frequency divided by 2.

It remains in that state till another MASTER RESET pulse is apply or the mode inputis a logic 1. The process starts by setting the AUTO RESET input (pin 5) to logic 0 and switching power on. If pin 5 is set to logic "1 , the AUTO RESET circuit is not enabled and counting cannot start till a positive MASTERRESET pulse is applied, returning to alow level. The AUTO RESET consumes a remarkable RC Oscillator Circuit. amount of power and should not be used if low- power operation is wanted. The frequency of the oscillator depends on the RC network.
