ULINK: JTAG PULL-UP RESISTORSInformation in this article applies to:
QUESTIONThe ULINK and ULINK2 User's Guides recommend using 100K pull-up resistors for JTAG signals TMS, TDI, TRST, and TCLK. But the Keil MCB2300 Evaluation Board uses 10K pull-up resistors, not 100K for those signals. Which one is correct? ANSWERYou may use either 10K or 100K resistors (or any value in between) as pull-ups for these JTAG signals. What's important is that you use them so they will keep the JTAG signals from floating when they are not connected to anything. MORE INFORMATION
