Data Sheet
ADuC7039
Rev. D | Page 23 of 92
In summary, there are three levels of protection as follows.
Temporary Protection
Temporary protection can be set and removed by writing
directly into FEEHID MMR. This register is volatile and,
therefore, protection is only in place for as long as the part
remains powered on. This protection is not reloaded after a
power cycle.
Keyed Permanent Protection
Keyed permanent protection can be set via FEEPRO to lock the
protection configuration. The software key used at the start of
the required FEEPRO write sequence is saved one time only
and must be used for any subsequent access of the FEEHID or
FEEPRO MMRs. A mass erase sets the software protection key
back to 0xFFFF but also erases the entire user code space.
Permanent Protection
Permanent protection can be set via FEEPRO, similarly to
keyed permanent protection, the only difference being that
the software key used is 0xDEADDEAD. When the FEEPRO
write sequence is saved, only a mass erase sets the software
protection key back to 0xFFFFFFFF. This also erases the entire
user code space.
Sequence to Write the Software Protection Key and Set
Permanent Protection
1. Write in FEEPRO corresponding to the pages to be protected.
2. Write the new (user-defined) 32-bit software protection
key in FEEADR (Bits[31:16]) and FEEDAT (Bits[15:0]).
3. Write 1, 0 in FEEMOD (Bits[6:5]) and set FEEMOD (Bit 3).
4. Run the Write Key Command 0x0C in FEECON.
To remove or modify the protection, the same sequence can be
used with a modified value of FEEPRO.
The previous sequence for writing the key and setting perma-
nent protection is illustrated in the following example, this
protects writing Page 8 to Page 11 of the Flash/EE.
Sequence Example
Int a = FEESTA;
// Ensure FEESTA is cleared
FEEPRO = 0xFFFFFFFB;
// Protect Page 8 to Page 11
FEEADR = 0x66BB;
// 32-bit key value (Bits[31:16])
FEEDAT = 0xAA55;
// 32-bit key value (Bits 15:0])
FEEMOD = 0x0048
// Lock security sequence
FEECON = 0x0C;
// Write key command
while (FEESTA & 0x04){}
// Wait for command to finish
