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.
