JTAG Port
Check
This option prevents the ISP software from detecting whether your
JEDEC file is using the JTAG port pins as logic I/O pins. The error
you would normally see when you attempt to program a device with
this type of design will be disabled. The default state of this option is
disabled. It will remain enabled until you disable it and vice versa.
If you decide to enable this option, be aware of the following
precautions:


After the device is programmed once, you will not be able to
re-execute any ISP operations on any devices in your JTAG hard-
ware chain. The only way to re-implement ISP on your JTAG chain is
to remove the affected device and erase it using an external device
programmer.
To enable/disable this option, do the following:
Before executing your chain file, hold down the [Shift] key and press
the [Alt] and [J] keys simultaneously. The Atmel-ISP software will dis-
play a warning message indicating the state of the JTAG port option
after you enter this key sequence. Click OK to close the warning
message.
Make sure you have first soldered an erased Atmel ISP device in
your JTAG hardware chain.
If you enable this option and still attempt to program any Atmel ISP
device, you will only be able to program it once using ISP.
