Re: AVR using JTag pins
I found in the JTagIce manual there is a section saying the following:
Figure 2-2 shows which JTAG lines should be connected to the target
AVR to ensure correct operation. To avoid drive contention on the
lines, place series resistors between the JTAG lines and external
circuitry. The value of the resistor should not exceed the maximum
ratings and sink or source to much current. See Section 5.4 for a
detailed description of the hardware.
Is it true to place series resistors between the JTAG lines and
external circuitry so that I can debug the IO pins using JTagICE?
