FTDI - BL vs. R

[Miroslav Sinko]

Hmm, neviem ci spravne chapem, ze vravite, ze stare FTDI cipy nemali
"citatelny" cfg. Mam svoj konfigurak od 245B, prikladam. Je z programu
MProg, pripona ept. 

Popis EEPROM struktury je napr. v ft245r09.pdf, ktory som namatkovo
nasiel u seba v archive. Pozor, to "r" neznamena 245R, dokument je
"FT8U245AM USB FIFO - Fast Parallel Data Transfer IC". V dokumente na
konci je Appendix B EEPROM Data Structure. Je to pre verziu "A",
predpokladam, ze verzia "B" to ma rovnako.
