9 years agoIs this a pretty old design? I suspect you have a design which relied on a stand alone programmer to configure the CPLD before it was assembled onto the PCB. MAX7000S devices could be programmed using a number of different programmers, made by both Altera and third parties. If the JTAG pins have been put to use as part of the original design then, I suspect, the device was originally programmed in such a manner.
Refer to the, pretty ancient, "altera programming hardware (http://www.altera.com/literature/ds/dspghd.pdf)" document. Cheers, Alex
