ABSTRACT:
A multi-memory function programmable counter or multi-memory function programmable timer capable of selectively assuming a plurality of counter or timer configurations. The main components of the present invention include a microprocessor, plurality of memory storage locations, and a keypad. Each of the plurality of memory storage locations stores a set of counter or timer function parameters and a preset count or time value, each of which defines a respective counter or timer configuration. The microprocessor includes a primary memory storage device for storing an operating system and a set of permissible values for a respective member of each set of the counter or timer function parameters. The keypad is coupled to the microprocessor to allow the user to select a value for each member of each set of counter or timer function parameters and for the preset count or time value. The value for each member of each set of counter or timer function parameters is selected from the set of permissible values. The keypad further allows the user to select one of the counter or timer configurations stored in a respective one of the plurality of memory storage locations. The microprocessor controls operation of the counter or timer in accordance with one of the counter or timer configurations selected by the user, such that the counter or timer is capable of readily assuming any one of the plurality of counter or timer configurations without the user having to reprogram the counter or timer.
