    Patent number: 5835503
    Abstract: A method and apparatus for serially programming or testing a programmable logic device. In one embodiment, the method comprises the steps of: instructing the programmable logic device, in one instruction, to load program data, load address information and program the program data into a memory location defined by the address information; loading the program data into a data storage element and the address information into an address storage element; and programming the program data into the memory location. The novel method further comprises the step of instructing the programmable logic device, in one instruction, to read verify data from the memory location, to compare the verify data with the program data and to program the program data into the memory location. The novel method further comprises the steps of comparing the verify data with the program data and generating a verify signal.
