Hi again....
Here comes my problem. I have FPGAs and PROMs on a pci card. I program them using JTAG. They use same TCK but TMS and TDI inputs are different. How can I give the BYPASS instruction to a device on the board. So that when the TCK comes the device stays unprogrammed. Anybody tell me the input sequence for TDI and TMS??? Thanks for your help...
(I think connecting TDI and TMS inputs to Vdd (logic1) makes the device stay unprogrammed although TCK clock comes. Am I right??)
