3.3.2 TPA0242 Module Jumper Settings and Switches

The TPA0242 EVM is equipped with a pushbutton SPST switch and a jumper

that acts as an SPST switch 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.
