Dear Freinds,
Hi,
I want to add a GTAG pin to my PCB using AT90can128, but I dont know the pin definitions of JTAG. I found that 8 bit microcontrolers use 10 pin JTAG interface.
I will be thankful If any body gives me a schematic of THE JTAG pins.
Greetings (No First Name Supplied),

BTW, I found the MkII ISP from Atmel to have sensitivity
to noise on the target’s power supply. This causes annoying
reboots of the ISP. (I did not have this issue with the MkI).
To solve it I added a 10K resistor and 10uF capacitor at
the ISP header (for the target’s power supply). You may
not need it, so leave the cap off and bridge the resistor,
but if you do need it the pads will be there.
