13.3.2 eFuse Reading Sequence
The read from the eFuse panel happens at boot time and the holding registers are loaded with the eFuse values. Therefore, the memory map of the eFuse is in 1:1 correspondence with the memory map of the holding registers. If required to verify the values in eFuse, reset the device after the eFuse programming sequence is done. The modified eFuse values are read from the eFuse and loaded on holding registers at boot-up. Read 13.4.1 Holding Registers (similar to the process for the peripheral registers), then verify these registers.
