; @Title: Generic script for Freescale MKV40 internal flash
;
; @Description:
; Example for flash declaration of Freescale MKV40 internal flash.
;
; Script arguments:
;
; DO mkv40 [PREPAREONLY] [CPU=<cpu>] [MASSERASE]
;
; PREPAREONLY only declares flash but does not execute flash programming
;
; CPU=<cpu> selects CPU derivative <cpu>
;
; MASSERASE forces mass erase of device before establishing debug connection
;
; Example:
;
; DO ~~/demo/arm/flash/mkv40 CPU=MKV40F64VLH15 PREPAREONLY
;
; List of MKV40 derivatives and their configuration:
;
; CPU-Type ProgFlash FlexNVM EEPROM RamSize
