Abstract:
A method includes loading a clock divider counter with most significant bits (MSBs) of a divider value, decrementing the counter at a same edge of each pulse of a clock signal, and comparing a value contained in the counter to a reference value and generating an end count signal if the value contained in the counter matches the reference value. If the value is even, the reference value is set to 1. If the value is odd, the reference value is set to 1, except for every other assertion of the end count signal, where the reference value is instead set to 0. A toggle signal transitions at a same edge of each pulse of the end count signal. The counter is reloaded with MSBs of the divider value based upon the end count signal. A divided version of the clock signal is generated based upon the toggle signal.
