Hi,

 

We have ADUCM320BBCZ program WRITE PROTECTION questions,

Could you help us to confirm the process?

  1. Write the “USER WRITE PROTECTIONPATTERN ADDRESS” (0x1FFF0 or 0x3FFF0) to FEEFLADR.

  2. Write the 64 bits(protect setting) to FEEFLDATA0 and FEEFLDATA1.

  3. Write the “write command” to FEECMD.

  4. Read the FEESTA register and receive 0x14

    [5:4] : 01: attempted signcheck, write, or erase of a protected location

       [2] : 1: set to 1 when a command completes

 

Is status of FEESTA correct or not?

Kevin Tsai
