If the TE USB FX2 module exit from reset or is powered on, the IIC EEPROM content programs/configures the USB FX2 microcontroller RAM |

The firmware actually changes (it is retrieved from EEPROM to RAM and it runs on USB FX2 microcontroller's RAM) only when
Note: the user writes the USB FX2 microcontroller's RAM (but the new firmware is lost if the TE USB FX2 module goes under reset or power off/on cycle)could write in RAM (and in EEPROM if he/she desires a permanent firmware change) to change the firmware running in the microcontroller if, for some reason, he/she cannot currently carry out a reset. |

It is an implicit (or explicit) step necessary to write a new firmware in the IIC EEPROM. See the section " (Implicit Two-Step) recovery boot and (Explicit Two-Step) recovery boot. |
