Appendix A - Cable EEPROM Configuration
Each C232HM MPSSE cable is controlled by the FTDI FT232H IC. This FT232H device contains an EEPROM
which contains the USB configuration descriptors for that device. When the cable is plugged into a PC or
a USB reset is performed, the PC will read these descriptors. The default values stored into the internal
EEPROM are defined in the following table
