Module efuse 

eFuse (one-time programmable configuration)

Overview

The efuse module provides functionality for reading eFuse data from the chip, allowing access to various chip-specific information such as:

• MAC address
• Chip revision

and more. It is useful for retrieving chip-specific configuration and identification data during runtime.
