Abstract
In a method and circuitry for variable single transition counting, a count signal (178) is provided on a count line. A direction control bit (264) is output on a direction control line. A significant bit (278e) is output on a significant bit line. A first single transition count (278a-d) is incremented in response to the count signal (178) and to the direction control bit (264) having an incrementing logic state. The first single transition count (278a-d) is decremented in response to the count signal (178) and to the direction control bit (264) having a decrementing logic state. The first single transition count (278a-d) and the significant bit (278e) together form a second single transition count (278a-e). The second single transition count (278a-e) is compared against a preselected value (296), and a comparison signal (320) is output in response to the second single transition count (278a-e) being equal to the preselected value (296 ). The direction control bit (264) and the significant bit (278e) are toggled in response to the comparison signal (320), such that a value of the second single transition count (278a-e) may be changed in response to the preselected value (296).
