MPM54304 Burning MTP memory

Hello,

im having some problems burning the I2C registers to the MTP table.

Ive been following the instructions from the datasheet and the draft: MPM54304 Password for writing to MTP memory

first im changing some I2C-registers.
Then im setting the MTP Programm Password and finally the MTP_Programm bit.

After restart the registers are still reset to default.

Is there a timing thing i need to watch out for? Or is the password maybe not up to date anymore?
Also what is the reason for writing and the overwriting the passwort register as descripted in: MPM54304 Password for writing to MTP memory
Am i maybe doing something wrong there?

Thanks in advance,
Joel
