Hi Alex,
I saw FTDI chip sends the address 0x4 and aduc7023 didn't ACK the address that is what I presumed wrong data on the data line. After that no activity on the bus and the error. Now if 0x80013 contains value other than 0XFF how do I remove that value? Is there anyway to get this i2c working on this one and get the mass chip erase?
Thanks.
