Philips Semiconductors Preliminary User Manual ARM-based Microcontroller Erase Sector(s) Table 192: IAP Erase Sector(s) command Command Erase Sector(s) Input Status Code Result None Description Blank check sector(s) Table 193: IAP Blank check sector(s) command Read Part Identification number LPC2131/2132/2138 Command code: 52 10 Param0: Start Sector Number Param1: End Sector Number: Should be greater than or equal to start sector number. Param2: System Clock Frequency (CCLK) in KHz. CMD_SUCCESS | BUSY | SECTOR_NOT_PREPARED_FOR_WRITE_OPERATION | INVALID_SECTOR This command is used to erase a sector or multiple sectors of on-chip Flash memory. The boot sector can not be erased by this command. To erase a single sector use the same "Start" and "End" sector numbers. Command Blank check sector(s) Input Status Code Result Description Command Code: 53 10 Param0: Start Sector Number Param1: End Sector Number (should be greater than or equal to the starting sector) CMD_SUCCESS | BUSY | SECTOR_NOT_BLANK | INVALID_SECTOR Table 194: IAP Read Part Identification command Result0: Offset of the first non blank word location if the Status Code is SECTOR_NOT_BLANK. Result1: Contents of non blank word location. This command is used to blank check a sector or multiple sectors of on-chip Flash memory. To blank check a single sector use the same "Start" and "End" sector numbers. Command Read part identification number Input Command Code: 54 10 parameters: None Status Code CMD_SUCCESS Result Result0: Part Identification Number Description This command is used to read the part identification number.

Philips Semiconductors Preliminary User Manual ARM-based Microcontroller Read Boot code version number Table 195: IAP Read Boot Code version number command Compare Reinvoke ISP Command Read boot code version number Input Command code: 55 10 Parameters: None Status Code CMD_SUCCESS Result LPC2131/2132/2138 Result0: 2 bytes of boot code version number in ASCII format. It is to be interpreted as . Description This command is used to read the boot code version number. Table 196: IAP Compare command Command Compare Input Status Code Command Code: 56 10 Param0 (DST): Starting Flash or RAM address of data bytes to be compared. This address should be a word boundary. Param1 (SRC): Starting Flash or RAM address of data bytes to be compared. This address should be a word boundary. Param2: Number of bytes to be compared; should be a multiple of 4. CMD_SUCCESS | COMPARE_ERROR | COUNT_ERROR (Byte count is not a multiple of 4) | ADDR_ERROR | ADDR_NOT_MAPPED Result Result0: Offset of the first mismatch if the Status Code is COMPARE_ERROR. Description Table 197: Reinvoke ISP Command Reinvoke ISP This command is used to compare the memory contents at two locations. The result may not be correct when the source or destination includes any of the first 64 bytes starting from address zero. The first 64 bytes can be re-mapped to RAM. Input Command Code: 57 10 Status Code None. Result None. Description This command is used to invoke the bootloader in ISP mode. This command maps boot vectors, configures P0.1 as an input and sets the vpb divider register to 0 before entering the ISP mode. This command may be used when a valid user program is present in the internal flash memory and the P0.14 pin is not accessible to force the ISP mode. This command does not disable the PLL hence it is possible to invoke the bootloader when the part is running off the PLL. In such case the ISP utility should pass the PLL frequency after autobaud handshake. Another option is to disable the PLL before making this IAP call.
