Abstract
Scanning circuitry 300 is provided which includes first input circuitry 302 which is operable to transfer bits of received data in response to a first clock signal. Second input circuitry 303 is also provided which is operable to transfer the bits of received data in response to a second clock signal. At least one first storage device 307 is provided which is operable to transfer bits of data received from the first input circuitry 302 in response to the first clock signal. At least one second storage device 308 is provided which is operable to transfer bits of data received from the second input circuitry 303 in response to the second clock signal. First output circuitry 309 is provided which is operable to transfer bits of data received from the at least one first storage device 307 in response to the second clock signal. Further, second output circuitry 310 is provided which shifts bits of data received from the at least one second storage device 308 in response to the second clock signal. A multiplexer 311 selects between bits of data received from the first output circuitry 309 and bits of data received from second output circuitry 310 in response to respective first and secon…
