Figure 2-10 Digital InterfaceThe digital signals are available on header J10 and an external microcontroller or USB2SPI software must be used to communicate with the device via SPI. The software development (SW) pin can be configured to active-high or active-low. The pin can be pulled high, pulled low, or left floating by using switch SW2.
By default, the SW pin is active-high. TI recommends to pull the SW pin high when beginning to work with the EVM to prevent watchdog errors from causing the device to repeatedly enter Restart Mode.
The nINT and GFO pins are also available on header J10.
