4.3 Target System – powered by the programmer
4.3.1 Overview
This section explains how the ‘Programmer Controlled Target Power Supply’ .can be used to
power the ‘customer target system’ .
4.3.2 Pre-set Output voltages
The programmer is capable of powering a customer ‘target system’ at one of four pre-defined
‘TVCC output voltages’ as defined in the table below…

5.0 5% 250
Please note:
The ‘programmer controlled – target power supply’ has a tolerance of approxi/- 5%, so
the generated voltage may not be the precise value of 3.0V, 3.3V, 4.7V or 5.0V specified in the
‘Target voltage settings’ in your project. It could be any voltage between the ‘Min’ and ‘Max’
voltages show in the table.
