Register 31: EEPROM Block Hide 1 (EEHIDE1), offset 0x054
Register 32: EEPROM Block Hide 2 (EEHIDE2), offset 0x058
The EEHIDE register is used to hide one or more blocks. Bits 0 through 31 of the EEHIDE1 register
correspond to EEPROM blocks 32 through 63. Bits 0 through 31 of the EEHIDE2 register correspond
to EEPROM blocks 64 through 95. 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.

Hide Block
DescriptionValue
The corresponding block is not hidden.0
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.
