3.3.2 TPA0202 Module Jumper Settings and Switches
The TPA0202 EVM is equipped with several pushbutton SPST switches and
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.
