Abstract
A data synchronization unit including first flip-flops, operating on a first clock domain and a reset of a second clock domain, sampling data from the first clock domain; a second flip-flop, operating in the first clock domain, sampling a request signal when enabled by a request pulse; a request signal path configured to delay the request signal by a first delay and to generate an enable signal for recirculation multiplexers in accordance with the delayed request signal; a reset signal synchronization path configured to delay the reset signal of the first clock domain by a second delay, wherein the second delay is shorter than the first delay; and multiplexers having first inputs for receiving outputs of the recirculation multiplexers, a second input for receiving a reset value of a programmable register, the multiplexers being configured to selectively output signals at inputs to outputs.
