Abstract:
1. A method of verifying programming of a non-JTAG device by a JTAG-compliant device, the JTAG-compliant device having: a first boundary scan shift register connected between a test-data-in terminal and a test-data-out terminal of the JTAG-compliant device; a second shift register connected between the test-data-in terminal and the test-data-out terminal; and a controller for communicating data between the second shift register and the non-JTAG device via a subset of boundary scan elements of the first boundary scan shift register, whereby each boundary scan element of the subset of boundary scan elements is directly coupled to a pin and each pin is directly coupled to the non-JTAG device to provide data to the non-JTAG device, the method comprising the steps of:
