Show checksum in status bar
After enabling of this setting the checksum of the code
memory will be shown on the status bar.
When MD5 checksum algorithm is selected, the checksum
is shown after placing the mouse on MD5 text in the
status bar.
Note: Doubleclick on the checksum value in the status bar
will cause the value recalculation.
Write checksum to log file
Enables writing of the loaded data file checksum to a log
file.
Note: The checksum is recalculated on data file load. This
function have to be enabled before the file load, else the
checksum value will not be written to the log file.
Checksum algorithm
Using this choice the checksum calculation algorithm can
be chosen.

Allow internal and external supply
voltages collision
Warning
A collision of power supply voltages can
damage the programmer or the application!
If you approve the collision of supply voltages, it allows
the programmer to connect its internal voltage to pin
VDD at times when it can already see a voltage present
there. This could damage both the programmer and/or
the application being programmed.
This option has been included for very specific cases. One
of them can be a request to program an application,
which does not have any VDD pin. Then the application
must be powered from its own source but the
programmer's output buffers must be powered from the
USB. Yet as the voltage at the application's data signals
“sneaks” through the protective diodes into the output
section of the programmer, the programmer can see a
certain small voltage present at VDD and refuses to
connect its own internal voltage to it.
Do not show warning if internal 5V is
switched on with 3.3V device
Warning
High a voltage at the device can damage the
programmer or the application being
programmed.
This option can be used to suppress the warning if a
higher voltage is switched on at the VDD output than the
value allowed for the particular device.
If there is a voltage convertor integrated in the
application between the device being programmed and
the programming interface, it might be useful to use this
option of programing at a higher voltage than what the
device has been designed for.
This option is available only for PRESTO.
Allow to change supply voltage level
when it is on
In order to protect the application connected to FORTE
from damage, it is typically forbidden to change the
output voltage level if the voltage is currently connected
to the application. After activating this option, the output
voltage can be changed at any time within the range that
Page 57
the device being programmed can cope with.
Allow external supply voltage for
devices requiring VPP before VCC.
For some devices their manufacturer requires the
programming voltage to be connected before the supply
voltage of the device. When the external supply voltage is
used, it does not comply with the specification. In this
case a warning is displayed, which can be permanently
disabled using this setting.
Disabling of this warning should be well considered. This
warning is displayed for devices for which the external
supply voltage violates the device manufacturer
specification.
When using Windows Messages
disable other warnings
When controlled via Windows Messages the UP software
does not show any warnings, similarly like in quiet mode
on the commandline.
Pin T during programming
With this setting it is possible to set a logical level during
programming on the T pin. The selected logical level will
be visible on the pin only when the supply voltage is
available at the VDD pin of the programmer.
In case that the T pin is used for programming, this
function will not be available.
This option is available only for FORTE.
Pin T after programming
With this setting it is possible to set a logical level, which
will appear on the T pin after programming. The selected
logical level will be visible on the pin only when the
supply voltage is available at the VDD pin of the
programmer.
In case that the T pin is used for programming, this
function will not be available.
This option is available only for FORTE.

Options Language selection...
Keyboard shortcut: Ctrl+L
A file with a different language localization can be
selected using the Windows standard dialog. This means
that one program installation can easily switch between
different user-interface languages.
Options Keyboard shortcuts...
Keyboard shortcut: Ctrl+K
Using this dialog window you can define or change
keyboard shortcuts for most commands the programmer
is capable of performing.
This window also provides for setting the required
behavior of the GO button.
Options Lock project
After a project file has been opened, it is locked against
unintentional changes. To unlock or lock it again this
function can be used.
When in project save dialog it was selected to Load
project unlocked, after load it will not be locked.

Power supply from the programmer
This trackbar allows the user to set the voltage level
supplied to the application by the programmer.
In idle state
If this option is checked, the programmer supplies power
to the application even when not programming.
During programming
If this option is checked, voltage from the programmer
will be used during programming.
Reset
This button allows you to switch levels on the device's
reset pin between the level required for reset and high
impedance.
Reset is active if voltage is present on the power supply
pin.

Microcontrollers
Protect with ID
If this option is active, it programs also the OSIS(ID) value
during Configuration memory programming, this way it is
possible to lock the device bootloader access.
Allow using Configuration Clearing
(erases TM, ID)
The Configuration Clearing erases a TM (Trusted Memory)
space. When the TM is in use, the use of this option
should be well considered.
The use of this option is the only possibility how to erase
OSIS(ID).
Baud Rate
Using this option it is possible to set a communication
speed between the programmer and the programmed
device.
