Flash Memory
MPC5606S Microcontroller Reference Manual, Rev. 7
Freescale Semiconductor 597
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 in low, mid and high address
space against program and erase.
17.3.4.2.1 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 usage of reserved Test flash sector is detailed in the following table.
When the Test space is enabled, all the operations are mapped to the Test block.
User mode program of the test block are enabled only when MCR.PEAS is high, also if the Shadow block
is available.
The Test flash block may be locked/unlocked against program by using the LML.TSLK and SLL.STSLK
registers. Erase of the Test flash block is always locked in user mode.
