hi,:)
One option would be to have a parallel load down counter driving a shift register.

Preload the counter, start a down clock to the counter, the clock also clocks the shift register, stops when the counter reaches zero.

Is this what you mean.?

oh...ok...i m trying it it out...thanks a ton:)

hi,
Lets know it goes.

If you want to shift a preloaded 'pattern' into the shift register, use a parallel to serial shift reg.

How about a serial in, parallel out SR with a multiplexer to select the "i"th output?
