8.5.1.2 Programming Register
There are altogether 126 programmable registers. However, not every register is required to be programmed at initial power-on.
For example, most of the registers have fixed field value which is also equal to their silicon default value. After programming R0 with RESET = 1, these register fields have returned to their silicon default values. As such, it is not necessary to program these registers again. Similarly, for those registers having configurable fields, if the desired field values are equal to the silicon default values, again it is not necessary to program these registers again after programming R0 with RESET = 1.
In Table 6, Depends means it is up to the user's decision of whether programming the register or not based upon the application need.
