; @Title: Generic script for NXP MKW30Z/MKW31Z internal flash
; @Description:
;   Script arguments:
;     DO mkw30 [PREPAREONLY] [CPU=<cpu>] [DUALPORT=<0|1>] [MASSERASE] ;
;       PREPAREONLY    only declares flash but does not execute flash programming
;       CPU=<cpu>      selects CPU derivative <cpu>
;       DUALPORT=<0|1> use dual port memory access, default 1
;       MASSERASE      forces mass erase of device before establishing debug
;                      connection
;   Example:
;     DO ~~/demo/arm/flash/mkw40z PREPAREONLY
;   Note:
;     This file must NOT be modified.
;     This file is intended to stay within TRACE32 installation.
;     Usage examples are available in the ~~/demo/arm/hardware/... subdirectories.
