; @Title: Example for flash declaration of Atmel ATSAML2 internal flash
; @Description:
;   Script arguments:
;
;    DO atsaml2 [PREPAREONLY] [CPU=<cpu>]
;
;      PREPAREONLY only declares flash but does not execute flash programming
;
;      CPU=<cpu> selects CPU derivative <cpu>
;
;   Example:
;
;   DO ~~/demo/arm/flash/atsaml2 CPU=ATSAML21E15A PREPAREONLY
;
;   List of ATSAML2* derivatives and their configuration:
;
