; 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

; 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.
