Abstract
A plurality of counters are connected with a plurality of correction terminals for independently correcting counts of the counters. An initializing circuit is connected between initializing terminals of the counters and the correction terminals. An initializing signal generator is connected between an input line from the power source and the correction terminals, for initializing the counters to predetermined counts only when signals are simultaneously applied to the correction terminals.
Claims7
An initializing circuit arrangement for a counter circuit comprising:
- a power source providing operating voltage between ground and supply terminals switch-connected to an input line;
- a plurality of counters each including an initializing terminal for setting its counter to a predetermined count in response to an initializing signal, each counter normally counting the number of external signals;
- independent correction terminals for at least two of the plurality of counters each correction terminal connected to means for correcting its counter in response to a correction signal on its correction terminal;
- an initializing circuit connected between the initializing terminal of each of the counters and said correction terminals;
- and
- an initializing signal generator means connected between said initializing circuit and said input line for generating said initializing signal upon connection to said power source.
