Flash Memory
MPC5606S Microcontroller Reference Manual, Rev. 7
Freescale Semiconductor 549
The flash module is divided into blocks also to implement independent erase/program protection. A
software 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 block
The Test flash block exists outside the normal address space and is programmed and read independently
of the other blocks. The independent Test flash block is included also to support systems which require
non-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.

Flash sector can be accessed via both slave ports. Arbitration logic required in case two different masters attempt
to access the same address at the same time.
