If an OTP configuration has not been programmed correctly in LAN7801, there is a way to disable it so that a new one can be programmed. (Look at the explanation from the first bye of the configuration)
This is described in the datasheet , section 10.2 under "application note" : change the byte 0 to 0xF7 and write new content starting from 0x101.
If you mess up the second one...then the device is not usable anymore
