- Switch 1 controls the MSP430 device on the board. If the switch is off, then the MSP430 is active and can initialize the board. If the switch is on, the MSP430 is held in reset so that it cannot be used. In other words, it is disabled to allow for a boot up from another device such as the EVM.
- As previously mentioned, three hosts can be used for I2C on the Fusion board. Switch 2 controls the host selection between the MSP430 (off), or the SoC/External on the EVM (on). If an external microcontroller is going to be used, see Section 3.1.1.
- The group of connectors (J28 to J35) that can be coax or HSD have a switch that must be thrown to activate the connection to be used. Switch 3 is used to toggle coax (on) or HSD (off). There cannot be a combination of coax and HSD on these connectors.
- Switch 4 is unused, there is no functionality.
