COPY_TO_RAM

If set, the boot loader copies the image to RAM at the address specified in the header. If not
set, the boot loader leaves the image in Flash. In both the instances, the boot loader
transfers control to the image entry point as specified in the header.

IMAGE_MCG

If set, the boot loader identifies the image as an Alternate MOTLoad image. If not set (as
well as IMAGE_POST flag not set), the boot loader identifies the image as a USER image.
This bit should not be set by developers of USER-type images.

IMAGE_POST

If set, the boot loader identifies the image as a Power On Self Test image. This flag is used
to indicate that the image is a diagnostic and would execute prior to executing USER or
Alternate MOTLoad images.

DONT_AUTO_RUN

If set, the boot loader ignores the image during the auto scan. A user may select the image
for execution through the interactive boot mode.

Note MOTLoad currently uses an Image Flag value of 0x3, which identifies itself as an Alternate
MOTLoad image that executes from RAM. MOTLoad currently does not support execution
from flash.
