The third set of API is a single API function: TE_USB_FX2_SendCommand(). This function is able to send the API commands to the EZ-USB FX2 microcontroller endpoint EP1 and receive the response binary code using endpoint EP1.

Using API command, TE_USB_FX2_SendCommand() is able to communicate with:

• the EZ-USB FX2 microcontroller endpoint EP1 (link); 
• the MicroBlaze implemented on the FPGA (link)
• the SPI Flash (link).

The connection with EP1 command is used to:

• send command to EZ-USB FX2 microcontroller (for example, reset the FPGA or power on/off the FPGA);
• interrogate registers;
• dipatching of API Commands to MicroBlaze and SPI Flash;
• read/write from MicroBlaze I2C bus address;
• read/write from SPI Flash.
