Register 26: EEPROM Block Hide (EEHIDE), offset 0x050
The EEHIDE register is used to hide one or more blocks other than block 0. Once hidden, the block
is not accessible until the next reset. This model allows initialization code to have access to data
which is not visible to the rest of the application. This register also provides for additional security
in that there is no password to search for in the code or data.

Value Description
0 The corresponding block is not hidden.
1 The block number that corresponds to the bit number is hidden.
A hidden block cannot be accessed, and the OFFSET value in
the EEBLOCK register cannot be set to that block number. If
an attempt is made to configure the OFFSET field to a hidden
block, the EEBLOCK register is cleared.
Any attempt to clear a bit in this register that is set is ignored.

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.
