The frequency of the oscillator is determined by the external components Rt and Ct within the frequency range 1 Hz to 100 kHz.
This oscillator may be replaced by an external clock signal at input RS, the timer advances on the positive-going transition of RS.
A LOW on the auto reset input (AR) and a LOW on the master reset input (MR) enables the internal power-on reset.
A HIGH level at input MR re...
