The dip switch, S3, has 4 switches. The switches labeled 3.3V (switch 3) and 5V (switch 4) pass the supply from the FTDI board micro-B receptacle from the BoosterPack header (J6) and vice versa. The Force Enable (switch 1 and switch 2) switch controls the reset on the FTDI device. When switch 1 is closed, the FTDI is held in reset until the TPS65988 has successfully loaded the firmware. When switch 2 is closed, the FTDI can be reset externally by pin 8 on the FTDI board header J7. By default, all switches are opened and in the upward position. Figure 5-13 highlights these features.
