; @Title: Example Script for programming of TI F28M35 Cortex-M3 internal flash
;
; @Description:
; Script arguments:
;
; DO f28m35 [PREPAREONLY] [AUTOECC=0|1] [DUALPORT=0|1]
;
; AUTOECC default value is 1
;
; PREPAREONLY only declares flash but does not execute flash programming example
;
; DUALPORT default value is 0 (disabled). If DualPort mode is enabled
; flash algorithm stays running until flash programming is
; finished. Data is tranferred via dual port memory access.
;
; Example:
;
; DO ~~/demo/arm/flash/f28m35 DUALPORT=1 AUTOECC=0 PREPAREONLY
;
; List of F28M35 derivatives and their configuration:
;
