security
The F2810 and F2812 support high levels of security to protect the user firmware from being reversed
engineered. The security features a 128-bit password, which the user programs into the Flash. One code
security module (CSM) is used to protect the Flash/OTP and the L0/L1 SARAM blocks. The security feature
prevents unauthorized users from examining the memory contents via the JTAG port, executing code from
external memory or trying to boot-load some undesirable software that would export the secure memory
contents. To enable access to the secure blocks, the user must write the correct 128-bit
KEY
value, which
matches the value stored in the password locations within the Flash.
Code Security Module Disclaimer
The Code Security Module (
CSM
) included on this device was designed to password
protect the data stored in the associated memory (either ROM or Flash) and is warranted

TI DOES NOT, HOWEVER, WARRANT OR REPRESENT THAT THE CSM CANNOT BE

REPRESENTATIONS CONCERNING THE CSM OR OPERATION OF THIS DEVICE,
INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR
A PARTICULAR PURPOSE.
IN NO EVENT SHALL TI BE LIABLE FOR ANY CONSEQUENTIAL, SPECIAL,
INDIRECT, INCIDENTAL, OR PUNITIVE DAMAGES, HOWEVER CAUSED, ARISING
IN ANY WAY OUT OF YOUR USE OF THE CSM OR THIS DEVICE, WHETHER OR NOT
