Timer circuit with programmable decode circuitry |
摘要 |
A timer circuit for providing output pulses of an adjustable duration based upon stored decode parameters. The circuit has a timer element which generates a periodic timing signal. Preferably the frequency of the periodic timing signal is also adjustable. A frequency divider is clocked by the timing signal and provides a plurality of frequency divided outputs. A decode circuit combines selected ones of the frequency divided outputs based upon decode parameters and generates a timer circuit output pulse having a duration determined by the frequency divided outputs selected by the decode parameters. The decode parameters are stored in a non-volatile data storage unit so that the timer output pulse will remain the same after power interruption.
