SPRS174T – APRIL 2001 – REVISED MAY 2012

NOTE

•

When the code-security passwords are programmed, all addresses between 0x3F 7F80

and 0x3F 7FF5 cannot be used as program code or data. These locations must be

programmed to 0x0000.

•

If the code security feature is not used, addresses 0x3F 7F80 through 0x3F 7FEF may

be used for code or data.

•

On ROM devices, addresses 0x3F 7FF2–0x3F 7FF5 and 0x3D 7BFC–0x3D 7BFF are

reserved for TI, irrespective of whether code security has been used or not. User

application should not use these locations in any way.

•

The 128-bit password (at 0x3F 7FF8–0x3F 7FFF) must not be programmed to zeros.

Doing so would permanently lock the device.
