SW1 is used to turn the ATX power supply ON. This switch is used only when the Tsi381 evaluation
board is powered up with a stand-alone ATX power supply.
SW2 is used to reset the evaluation board. When pushing the reset button, the board is reset the same
way a PCIe system reset would reset the board.
