Abstract

An apparatus comprising a first circuit, a second circuit and a third circuit. The first circuit may be configured to generate (i) one or more first enable signals and (ii) one or more first flag signals in response to a first clock signal and a second enable signal. The second circuit may be configured to generate a second flag signal in response to (i) the one or more first enable signals, (ii) the one or more first control signals, (iii) a second clock signal, and (iv) a pulse signal. The third circuit may be configured to generate the pulse signal in response to (i) a third clock signal and (ii) the one or more first flag signals.
