|
; 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.
