Flash MemoryMPC5606S Microcontroller Reference Manual, Rev. 7Freescale Semiconductor 549The flash module is divided into blocks also to implement independent erase/program protection. Asoftware mechanism is provided to independently lock/unlock each block (as reported in Table 17-1)against program and erase.17.2.4.2.1 Test flash blockThe Test flash block exists outside the normal address space and is programmed and read independentlyof the other blocks. The independent Test flash block is included also to support systems which requirenon-volatile memory for security and/or to store system initialization information.A section of the Test flash is reserved to store the non-volatile information related to redundancy,configuration, and protection.The ECC is applied also to Test flash.The use of the reserved Test flash sector is detailed in the following table.0x00400000 0x00403FFF 16 Yes Yes Yes — Code Flash Array 0 Test Sector0x00404000 0x0047FFFF 496 — — — — Reserved0x00480000 0x00483FFF 16 No No Yes — Code Flash Array 1 Test Sector0x00484000 0x007FFFFF 3568 — — — — ReservedOn-chip Flash Memories (Data Flash)0x00800000 0x00803FFF 16 Yes Yes Yes B1F0 Data Flash Array 00x00804000 0x00807FFF 16 Yes Yes Yes B1F1 Data Flash Array 00x00808000 0x0080BFFF 16 Yes Yes Yes B1F2 Data Flash Array 00x0080C000 0x0080FFFF 16 Yes Yes Yes B1F3 Data Flash Array 00x00810000 0x00BFFFFF 4032 — — — — ReservedOn-chip Flash Memories (Test for Data Flash)0x00C00000 0x00C03FFF 16 Yes yes Yes — Data Flash Array 0 Test Sector0x00C04000 0x00FFFFFF 2032 — — — — Reserved1 Flash sector can be accessed via both slave ports.
