what does the enable pin do? clock inhibit? carryout?

i've used these to continuously count, but now i need it to just count once.

so in the past ive gone
1 2 3 4 5 6
1 2 3 4 5 6
1 2 3 4 5 6

but now i need
1 2 3 4 5 6
(wait for another input pulse)

how do i do this?

thanks

If you feed the 6 output back to clock enable, it will stop until you give it a reset pulse. Is that what you want?

ok, so first, how do i take an input pulse to start the counting cycle? connect that incoming pulse to reset?

i guess i dont understand reset.... does it make the counter = 0 ? or does it start the counting? and same with enable?

When RESET is high, all outputs are set to zero (low). Both reset and clock enable must be low for the counter to count clock pulses. When clock enable goes high, the count stops even tho the clock pulses continue. If you connect the 6 output to clock enable, then you can start the count by taking reset high momentarily. When reset goes low, the count starts. When output 6 goes high, the count stops.
