; @Title: Example for flash declaration of NXP LPC17xx internal flash.
;
; @Description:
; Script arguments:
;
; DO lpc17xx [PREPAREONLY] [CPU=<cpu>]
;
; PREPAREONLY only declares flash but does not execute flash programming
; example
;
; CPU=<cpu> selects CPU derivative <cpu>
;
; Example:
;
; DO ~~/demo/arm/flash/lpc17xx CPU=LPC1788 PREPAREONLY
;
; List of LPC17xx derivatives and their configuration:
;

; Code Read Protection (CRP):
;
; CRP is invoked by programming a specific pattern in flash location
; at 0x000002FC.
;
; Name Pattern Description
; --------------------------------
; CRP1 0x12345678 Access to chip via the JTAG pins is disabled. This
; mode allows partial flash update using the following
; ISP commands and restrictions:
; * Write to RAM command can not access RAM below
; 0x10000200.
; This is due to use of the RAM by the ISP code.
; * Read Memory command: disabled.
; * Copy RAM to Flash command: cannot write to Sector 0.
; * Go command: disabled.
; * Erase sector(s) command: can erase any individual
; sector except sector 0 only, or can erase all
; sectors at once.
; * Compare command: disabled
; This mode is useful when CRP is required and flash
; field updates are needed but all sectors can not be
; erased. The compare command is disabled, so in the
; case of partial flash updates the secondary loader
; should implement a checksum mechanism to verify the
; integrity of the flash.
; CRP2 0x87654321 This is similar to CRP1 with the following additions:
; * Write to RAM command: disabled.
; * Copy RAM to Flash: disabled.
; * Erase command: only allows erase of all sectors.
; CRP3 0x43218765 This is similar to CRP2, but ISP entry by pulling
; P2.10 LOW is disabled if a valid user code is present
; in flash sector 0. This mode effectively disables ISP
; override using the P2.10 pin. It is up to the user's
; application to provide for flash updates by using IAP
; calls or by invoking ISP with UART0.
; Caution: If CRP3 is selected, no future factory
; testing can be performed on the device.
;
; HINTS:
;
; Flash clock has to match System Clock Frequency (CCLK).
; FLASH.CLocK.AUTO can be used for automatic flash clock measurement.
;
; Boot flash cannot be programmed or erased with builtin flash
; algorithm.
;
; Data has to be loaded to flash alignment to page boundaries.
;
; Vector table checksum generation is done by script, so that it
; can be used or switched off, as needed.
