3.3.2 TPA0122 Module Jumper Settings and Switches
The TPA0122 EVM is equipped with a pushbutton SPST switch and three
jumpers that act as SPST switches to allow module operation to be modified
to suit various requirements. In the following discussion, setting a jumper to
ON means that a shunt is installed across the two pins of the jumper. Setting
a jumper to
OFF means that no shunt is installed on the jumper. See
Figure 3.5.
In typical applications, some or all of the jumper functions are controlled by the
system microcontroller or external logic.
