When power is supplied to J3, JMP1 allows for one of two different DC voltages to be selected as power
for the TSC. See the schematic and PCB silkscreen for details.

The TSC2008EVM-PDK motherboard (the USB-MODEVM interface board) supplies power to J3 of the
TSC2008EVM. Power for the motherboard is supplied either through its USB connection or via terminal
blocks on the board.

can be supplied either from the +1.8VD terminal or from the +3.3VD terminal.
JMP1 selects which of these voltages is routed to the TSC2008. When JMP1 is in the default factory
condition (shunt on pins 2-3), power to the TSC comes from J3.9 (+3.3VD). When the shunt is installed on
JMP1 pins 1-2, power comes from J3.7 (+1.8VD). Removing the shunt on JMP1, the user can connect
any DC power supply between 1.2VD and 3.6VD to VCC by connecting the power to JMP1 pin 2.
