AN949: TouchXpress™ Programming
Guide
This application note gives an overview of the programming op-
tions available for Silicon Labs TouchXpress CPT devices.
The two main categories for programming devices are in-system programming and pre-
programming. The most appropriate type of programming depends on the number of
devices being programmed and whether access is available to the configuration pins of
the device. Additional information on production programming for Silicon Labs in gener-
al can be found on the website:

KEY POINTS
• When programming a device in-system, it
is necessary that the ToolStick and the
device being programmed share a
common ground.
• Third-party programmers and pre-
programming are also options available for
programming production devices.
