Abstract

An input/output circuit in an In-system programmable (ISP) logic device allows an output signal from a boundary scan register to be provided as output during programming operations of said ISP logic device. Thus, the ISP logic circuit can provide valid data output to other circuits interfaced to the ISP logic circuit during programming of the ISP logic device, thereby obviating a need to reset the system after reprogramming of the ISP logic device.
