Abstract

A clock divider and method of operating the same. In various embodiments, the clock divider may be configured to divide clock frequencies by both even and odd divisors. The divisor may be an integer that is represented by an N-bit value, and the clock divider may be programmable by writing the N-bit value to a register. The divisor may be even or odd. During operation, the clock divider may decrement a counter down from an initial value (derived from the N-bit value representing the divisor) to a trigger value. When the trigger value is detected, the clock divider may cause the output clock to toggle. The trigger value may depend on whether the divisor is even or odd. The clock divider may be re-programmed during operation by writing a new N-bit value into the register. Re-programming may include changing the divisor from an even value to an odd value.
