-====== Efuse ======
-===== Efuse blocks =====
-ESP32 has 4 eFuse blocks each containing 256 bits (not all bits can be used for user parameters):
-  - EFUSE_BLK0 is used entirely for system purposes
-  - EFUSE_BLK1 is used for Flash Encryption keys. If the Flash Encryption feature is not used, this block can be used for user parameters.
-  - EFUSE_BLK2 is used for the Secure Boot key. If the Secure Boot feature is not used, this block can be used for user parameters.
-  - EFUSE_BLK3 can be partially reserved to store a custom MAC address, or can be used entirely for user parameters. Note that some bits are already used in ESP-IDF.
-The content of various blocks could be found at:
