4.3.1.3
When the e500 core comes out of reset, its MMU has one 4-Kbyte page defined at 0x0_FFFF_Fnnn. The
core begins execution with the instruction at effective address 0x0_FFFF_FFFC. To get this instruction,
the core’s first instruction fetch is a burst read of boot code from effective address 0x0_FFFF_FFE0. For
systems in which the boot code resides at a different address, the MPC8533E provides boot page
translation capability. Boot page translation is controlled by the boot page translation register (BPTR).
The boot sequencer can enable boot page translation, or the boot page translation can be set up by an
external host when the MPC8533E is configured to be in boot holdoff mode. If translation is to be
performed to a page outside the default boot ROM address range defined in the MPC8533E (8 Mbytes at
0x0_FF80_0000 to 0x0_FFFF_FFFF as defined in
host or boot sequencer must then also set up a local access window to define the routing of the boot code
fetch to the target interface that contains the boot code, because the BPTR defines only the address
translation, not the target interface. See
