Boot ROM
This mode supports booting from the following:
In slave mode, the MCF5253 will wait for communication from a controlling MCU and store the code it
receives in RAM. It executes this code after receiving an execute command. The controlling MCU must
control the data transfer and handle error recovery if required.
This mode supports booting from the following:
19.2
19.2.1
19.2.1.1
19.2.1.2
The boot ROM data resides in the upper range of the internal SRAM.
The SRAM allocation is as follows:
0x1001FC90 – 0x1001FF13Bootloader uninitialized data (HDD) (644 bytes)
0x1001FF14 – 0x1001FF3FBootloader uninitialized data (Serial) (44 bytes)
0x1001FF40 – 0x1001FFFFBootloader Stack (192 bytes)

Internal SRAM usage
The HDD data space is available for use when booting from a serial device.
If the user routine exceeds the assigned stack allocation, then it would be
more appropriate for the user to define their own stack space, especially if
the user routine returns to the bootloader.
