About
Atmel-ISP
There are many protection features built in to the Atmel-ISP software. For example, fea-
tures to ensure that the correct device is being programmed, that the correct voltage
level is being applied to the ISP device, that the JTAG port will not be disabled after pro-
gramming. To allow advanced users to override some of these built-in protection
features, hidden commands are made available in order to allow these advanced users
to force the ISP operation to proceed despite the fact that ATMISP detected potential
problems. Please use these hidden commands with discretion. These hidden com-
mands are listed and described below.

This command displays the table of contents of this Help file.
This command displays the version number of the Atmel-ISP soft-
ware you are currently using. If you are unsure whether you have the
latest version, check with Atmel PLD Applications.
This option allows you to override the ISP software setting that
checks the correct manufacturer ID for Atmel ISP devices. If you
receive the ID Check error, you can use this command to bypass the
manufacturer ID check process. The default setting for this option is
disabled. This option will remain enabled until you disable it and vice
versa, if it is disabled.
To enable/disable this option, do the following:


This option overrides the normal error message you would receive
from the ISP software when you attempt to program both 3V and 5V
Atmel devices in the same JTAG hardware chain. The default state of
this option is disabled. It remains enabled until you disable it and vice
versa.
If you decide to enable this option, please be aware of the following
precautions:




To enable/disable this option, do the following:


Before executing your chain file, hold down the [Shift] key and
press the [Alt] and [L] keys simultaneously. The Atmel-ISP software
will display a warning message indicating the state of the
manufacturer ID Check option after you enter this key sequence.
Click OK to close the warning message.
5V device may not program correctly with a 3V supply. This may
create functional problems with your board.
Interfacing 3V and 5V devices on the same board may create
problems if your 3V devices are not completely 5V tolerant. This
may cause functional problems on your board.
Before executing your chain file, hold down the [Shift] key and
press the [Alt] and [V] keys simultaneously. The Atmel-ISP software
will display a warning message indicating the state of the JTAG port
option after you enter this key sequence. Click OK to close the
warning message.
