6. Internal EEPROM Configuration
Following a power-on reset or a USB reset the FT232R will scan its internal EEPROM and read the USB configuration
descriptors stored there. The default values programmed into the internal EEPROM in the FT232RL used on the
UC232R are shown in Table 2.
Table 2 - Default Internal EEPROM Configuration
The internal EEPROM in the FT232R can be programmed over USB using the utility program MPROG. MPROG can
be downloaded from the
