MPM54304 Programming Sequence

I wanted to change one value in the MPM54304-0003. Do I need to copy all of the register values to the MTP registers starting at 0x40 or is updating the I2C Registers only, at 0x00?
How long does programming take?
How much current does the MPM5403 take during programming?
I tried to update the MPM5403-0003 but it came up with junk data in all of the registers and I have only one more try before the part is scrapped and I nave to replace it.

Hello wbarrow,

Are you using an evb to do this? I don’t think it requires all of the registers to be copied.
