MPM54304GMN safe mode MTP

Hello,
I try programing MTP in MPM54304, in datasheet says i need to start up in "safe mode " (page 20).
When i connect external 5V in to EN/SYNC pin, then i apply 12 V to Vin, my converter staring normally, all of 4 converters working properly and produce a nominal voltages. Is not a “safe mode” operation what i do wrong ?
Next i see some MTP topic on forum but i don’t know what is strange registers in I2C like (0x95 of one in topic forum ??).

Bellow is example of my sending formula :

send(0x05,0x2D); // set BUCK2 3V3 → 1V

register 0x05 it’s buck2 config 2D mean 0b00101101 (VREF table it is 1V ) bulked 0 is a multiplayer wich is 1

And it’s working properly.
What i need to do to program MTP (i try once but i bricked my ic them i replace to new one).

Thanks for help
Karol

Hi Karol,

It will automatically start up in safe mode when Vin powers up and EN is pulled high.
Please follow the steps on page20 for MTP.
