10. Internal EEPROM Configuration
Following a power-on reset or a USB reset the FT245R will scan its internal EEPROM and read the USB configuration
descriptors stored there. The default values programmed into the internal EEPROM in a brand new device are defined
in Table 19.
Table 19 - Default Internal EEPROM Configuration
The internal EEPROM in the FT245R can be programmed over USB using the utility program MPROG. MPROG can
be downloaded from the
