; Code Read Protection (CRP):
;
; CRP is invoked by programming a specific pattern in flash location
; at 0x000002FC.
;
; Name Pattern Description
; --------------------------------
; NO_ISP 0x4E697370 Prevents sampling of pin PIO0_1 for entering ISP mode.
; PIO0_1 is available for other uses.
; CRP1 0x12345678 Access to chip via the SWD pins is disabled. This mode
; allows partial flash update using the following ISP
; commands and restrictions:
; * Write to RAM command should not access RAM below
; 0x10000300. Access to addresses below 0x10000200 is
; disabled.
; * Copy RAM to flash command can not write to Sector 0.
; * Erase command can erase Sector 0 only when all
; sectors are selected for erase.
; * Compare command is disabled.
; * Read Memory command is disabled.
; This mode is useful when CRP is required and flash
; field updates are needed but all sectors can not be
; erased. Since compare command is disabled in case of
; partial updates the secondary loader should implement
; 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 Access to chip via the SWD pins is disabled. ISP entry
; by pulling PIO0_1 LOW is disabled if a valid user code
; is present in flash sector 0.
; This mode effectively disables ISP override using PIO0_1
; pin. It is up to the user's application to provide a
; flash update mechanism using IAP calls or call reinvoke
; ISP command to enable flash update via UART.
; CAUTION: If CRP3 is selected, no future factory testing
; can be performed on the device.
;
; RAM used by IAP command handler:
;
; IAP commands, which results in a flash write/erase operation, use 32 bytes of
; space in the top portion of the on-chip RAM for execution.
;
; 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.
