Chapter 19 Flash Module (S12ZFTMRZ)MC9S12ZVMB Family Reference Manual Rev. 1.3NXP Semiconductors 64719.4.5.4 P-Flash CommandsTable 19-30 summarizes the valid P-Flash commands along with the effects of the commands on the P-Flash block and other resources within the Flash module.19.4.5.5 EEPROM CommandsTable 19-31 summarizes the valid EEPROM commands along with the effects of the commands on theEEPROM block.Table 19-30. P-Flash CommandsFCMD Command Function on P-Flash Memory0x01 Erase Verify AllBlocksVerify that all P-Flash (and EEPROM) blocks are erased.0x02 Erase Verify Block Verify that a P-Flash block is erased.0x03 Erase Verify P-Flash SectionVerify that a given number of words starting at the address provided are erased.0x04 Read Once Read a dedicated 64 byte field in the nonvolatile information register in P-Flash block thatwas previously programmed using the Program Once command.0x06 Program P-Flash Program a phrase in a P-Flash block.0x07 Program Once Program a dedicated 64 byte field in the nonvolatile information register in P-Flash blockthat is allowed to be programmed only once.0x08 Erase All BlocksErase all P-Flash (and EEPROM) blocks.An erase of all Flash blocks is only possible when the FPLDIS, FPHDIS, and FPOPENbits in the FPROT register and the DPOPEN bit in the DFPROT register are set prior tolaunching the command.0x09 Erase Flash BlockErase a P-Flash (or EEPROM) block.An erase of the full P-Flash block is only possible when FPLDIS, FPHDIS and FPOPENbits in the FPROT register are set prior to launching the command.0x0A Erase P-FlashSectorErase all bytes in a P-Flash sector.0x0B Unsecure Flash Supports a method of releasing MCU security by erasing all P-Flash (and EEPROM)blocks and verifying that all P-Flash (and EEPROM) blocks are erased.0x0C Verify BackdoorAccess KeySupports a method of releasing MCU security by verifying a set of security keys.0x0D Set User MarginLevelSpecifies a user margin read level for all P-Flash blocks.0x0E Set Field MarginLevelSpecifies a field margin read level for all P-Flash blocks (special modes only).0x13 ProtectionOverrideSupports a mode to temporarily override Protection configuration (for P-Flash and/orEEPROM) by verifying a key.
