FUSE_PORx bits of MMPF0100.

Hi community,

I have a question about MMPF0100.

MMPF0100 has FUSE_PORx bits , however there is no description about these bits in MMPF0100 datasheet (Rev.7.0).

Could you let me know the function of these bits?

OTP fuse bit FUSE_POR can be blown so that upon subsequent power cycles, the start-up sequence

is chosen from the OTP fuses and not from the TBBOTP registers.

Hi Yuri,

Thank you for your reply.

Then, I want t to know the difference between FUSE_POR1, FUSE_POR2, and FUSE_POR3 also.

I guess the start-up sequence is defined as below.

If this is correct, there is no difference between FUSE_POR1, FUSE_POR2, and FUSE_POR3.

Is this right?

Correct, any of the FUSE_PORx may be used, no difference between them.
