PIO0_12 is available for other uses. ; 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 cannot access RAM below ; 0x10000300. ; • 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. ; CRP2 0x87654321 Access to chip via the JTAG 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 JTAG pins is disabled. ISP ; entry by pulling PIO0_12 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: ; ; Flash programming commands use the top 32 bytes of on-chip RAM. ; The maximum stack usage in the user allocated stack space is 128 ; bytes and it grows downwards. ; ; 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. ; ; @Author: WRD ; @Copyright: (C) 1989-2019 Lauterbach GmbH, licensed for use with TRACE32(R) only ; @Chip: LPC12* ; -------------------------------------------------------------------------------- ; $Rev: 7605 $ ; $Id: lpc12xx.cmm 7605 2019-11-05 16:45:28Z bschroefel $ LOCAL ¶meters ¶m_prepareonly ENTRY %LINE ¶meters ¶m_prepareonly=(STRing.SCAN(STRing.UPpeR("¶meters"),"PREPAREONLY",0)!=-1) LOCAL ¶m_cpu ¶m_cpu=STRing.SCANAndExtract(STRing.UPpeR("¶meters"),"CPU=","") ; ------------------------------------------------------------------------------ ; Start debugging IF SYStem.MODE()<5 ( SYStem.RESet IF "¶m_cpu"!="" SYStem.CPU ¶m_cpu IF !CPUIS(LPC12*) ( IF VERSION.BUILD()>=37389.
