Abstract
A ripple counter becomes programmable by use of intervening circuitry selectively inhibiting state transitions according to an initial programming step. The illustrated embodiment of a programmable ripple counter includes a forward chain of count registers operating generally in the fashion of a ripple counter, but selectively inhibited by an intervening control signal originating from a reverse chain of control registers. By selectively controlling the number of state transitions inhibited and by selectively controlling the number of registers participating in the counting operation, a low power general purpose programmable ripple counter results.
