EEPROM Debug Mass Erase (EEDBGME)
The EEDBGME register is used to mass erase the EEPROM block back to its default state from the factory. This register is intended to be used only for debug and test purposes, not in production environments. The erase takes place in such a way as to be secure. It first erases all data and then erases the protection mechanism. This register can only be written from supervisor mode by the core, and can also be written by the debug controller when enabled. A key is used to avoid accidental use of this mechanism. Note that if a power down takes place while erasing, the mechanism should be used again to complete the operation. Powering off prematurely does not expose secured data.
To start a mass erase, the whole register must be written as 0xE37B0001. The register reads back as 0x1 until the erase is fully completed at which time it reads as 0x0. The EEDONE register is set to 0x1 when the erase is started and changes to 0x0 or an error when the mass erase is complete.
EEDBGME is shown in Figure 7-39 and described in Table 7-40.
