; @Title: Flash declaration for ST STM32G4 internal flash
; @Description:
; Script arguments:
; DO stm32g4 [PREPAREONLY] [CPU=<cpu>] [DUALPORT=<0|1>]
; 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
; Example:
; DO ~~/demo/arm/flash/stm32g4 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.
