====== Features and Overview ======

The SDK implements FPGA Board specific functions in the firmware and allows to access them using the host software API. 
These functions are:
  * Firmware upload directly to the EZ-USB FX2 and FX3 Microcontrollers
  * Access to SPI-Flash
  * FX2: Access to EEPROM
  * Firmware upload to EEPROM (FX2) and Flash (FX3)
  * FX2: Access to microSD/*SD/MMC Flash cards in SPI mode
  * FX3S: Access to SD card (SDIO and other functions usable with the Cypress SDK)
  * Bitstream upload directly to the FPGA
  * Bitstream upload to Flash memory
  * Automatic Bitstream loading from Flash during start-up
  * MAC-EEPROM support, used to store configuration data

A more detailed feature description can be found on the [[http://www.ztex.de/firmware-kit/|ZTEX Homepage]]. 

An overview about the usage of the different parts of the ZTEX EZ-USB SDK is given by the following diagram.
