Relationship between trim with OTP?

[k23428]

I am confused by the following description on page 15, datasheet of PF8100/PF8200.

1.What is the "trim"? What is the relationship between trim with OTP? 

2.How to understand “fuse”？Does “fuse” refer to the parameter to be written into the register ？

2.What is the mirror register？What is the relationship between mirror egister with I2C register?

1: trim means change/update/modify OTP register content.

2: You can understand fuse as box,you can put your desired content into box for PMIC configuration.

3:OTP mirror register please refer to datasheet page98- 16.2 PF8200 OTP mirror register map (page 1)
