Examples of protect start address:
Freescale Semiconductor
The resultant 16-bit address is used for specifying the start address of the FLASH memory for block
protection. The FLASH is protected from this start address to the end of FLASH memory, at $FFFF.
With this mechanism, the protect start address can be XX00, XX40, XX80, or XXC0 (at page
boundaries — 64 bytes) within the FLASH memory.
