; @Title: Flash declaration for NXP LPC54xxx Cortex-M4 internal flash
; @Description:
; Reprogam internal Flash of NXP LPC54xxx.
; Script arguments:
; DO lpc54xx [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/lpc54xx CPU=LPC54102J512UK49-M4 PREPAREONLY
; Note : Flash programming must be done from a Cortex-M4
;
; List of LPC40xx derivatives and their configuration:

; Flash characteristics:
; Page size 256 Byte
; Sector size 32 KB
;
; Code Read Protection (CRP):
; CRP is invoked by programming a specific pattern in flash location
; 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
; 0x02000300.
; Read Memory command: disabled.
; Copy RAM to Flash command: cannot write to Sector 0.
; 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 Access to chip via the SWD pins is disabled.
; The following ISP commands are disabled:
; Read Memory
; Write to RAM
; Go
; Copy RAM to flash
; Compare
; When CRP2 is enabled the ISP erase command only allows
; erasure of all user 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.
;
; Flash programming commands use 32 bytes of space in the top portion of the
; on-chip SRAM0 0x0200FFE0-0x0200FFFF for execution.
;
; Hints:
; Flash clock has to match System Clock Frequency (M4_CLK).
; 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 into flash aligned to page boundaries.
