Register 21: EEPROM Protection (EEPROT), offset 0x030
The EEPROT register is used to set or read the protection for the current block, as selected by the
EEBLOCK register. Protection and access control is used to determine when a block's contents
can be read or written. The protection level for block 0 sets the minimum protection level for the
entire EEPROM. For example, if the PROT field is configured to 0x1 for block 0, then block 1 could
be configured with the PROT field to be 0x1, 0x2, or 0x3, but not 0x0.

Reset Description
RO 0x0000.000 Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Access Control
Value Description
0 Both user and supervisor code may access this block of the
EEPROM.
1 Only supervisor code may access this block of the EEPROM.
μDMA and Debug are also prevented from accessing the
EEPROM.
If this bit is set for block 0, then the whole EEPROM may only be
accessed by supervisor code.
