SPRS439M –JUNE 2007–REVISED AUGUST 2012

NOTE

• When the code-security passwords are programmed, all addresses between 0x33FF80

and 0x33FFF5 cannot be used as program code or data. These locations must be

programmed to 0x0000.

• If the code security feature is not used, addresses 0x33FF80 through 0x33FFEF may be

used for code or data. Addresses 0x33FFF0–0x33FFF5 are reserved for data and should

not contain program code.

The 128-bit password (at 0x33 FFF8–0x33 FFFF) must not be programmed to zeros. Doing

so would permanently lock the device.
