224 The FT232R chip has an internal eeprom.
225 An external serial eeprom is optional on other FTDI chips.
226 The eeprom may contain 64, 128, or 256 words,
229 When no eeprom is present, all words in the returned data are 0xffff.
230 An erased eeprom also reads as all 0xffff.
232 Write one or more words to the configuration eeprom.
238 The FTDI chip does a blind write to the eeprom, and it will appear
239 to succeed even when no eeprom is present.
244 Any position within the eeprom can be overwritten at any time.
246 Erase the entire eeprom.
