Abstract
A counter circuit selectively generates counting sequences in binary and interleave counting modes. A counter is formed by 3 toggle flip-flops. The toggle signals are provided by a toggle control circuit which contains logic gates that are enabled or disabled based on the state of a mode select signal. In binary mode, output bits are permitted to be used to toggle higher order count stages. In interleave mode, the binary toggle signals are blocked, and another counter circuit counts toggle signals in the interleave sequence, which signals are passed by the toggle control circuit to toggle inputs of the main counter. The other counter circuit can be reset in response to a reset signal applied to a load enable input.
