- ;// DESCRIPTION:
- ;//
- ;// This file is used to specify password values to

- ;// at 0x3F7FF8 - 0x3F7FFF.
- ;//
- ;// In addition, the reserved locations 0x3F7F80 - 0X3f7ff5 are
- ;// all programmed to 0x0000

- ; The "csmpasswords" section contains the actual CSM passwords that will be
- ; linked and programmed into to the CSM password locations (PWL) in flash.
- ; These passwords must be known in order to unlock the CSM module.
- ; All 0xFFFF's (erased) is the default value for the password locations (PWL).
- ; It is recommended that all passwords be left as 0xFFFF during code
- ; development. Passwords of 0xFFFF do not activate code security and dummy
- ; reads of the CSM PWL registers is all that is required to unlock the CSM.
- ; When code development is complete, modify the passwords to activate the
- ; code security module.

- ; For code security operation, all addresses between 0x3F7F80 and
- ; 0X3f7ff5 cannot be used as program code or data. These locations
- ; must be programmed to 0x0000 when the code security password locations
- ; (PWL) are programmed. If security is not a concern, then these addresses
- ; can be used for code or data.
- ; The section "csm_rsvd" can be used to program these locations to 0x0000.
