ETRA family uses the Bank0 Word 57, Word 58 for storing the MAC addresseaddress. The MAC values should be properly divided into the in two registers for correct programming.
The related 57, 58, OTP registers will be used for the purposes illustrated in this AN.
{{ImportantMessage|text='''Warning!!''' eFuse programming is a permanent and non -reversible action. Pay attention to the values and commands used during MAC programming.}}
