Measurement initialization circuitry is described. Propagation of a start signal through a variable delay line may be stopped by either of two stop signals. One stop signal corresponds to a rising edge of a reference clock signal. A second stop signal corresponds to a falling edge of the reference clock signal. The start signal propagation is stopped responsive to the first to arrive of the first and second stop signals. Accordingly, in some examples, start signal propagation through a variable delay line may be stopped responsive to either a rising or falling edge of the reference clock signal. |
