part of the SDK in this case.

If user mode is enabled, and MPU hardware has requirements that
|
|
regions be sized to a power of two and aligned to their size,
|
|
and user mode threads need to access this heap, then this is necessary
|
|
to properly define an MPU region for the heap.
|
|
|
|
If this is left at 0, then remaining system RAM will be used for this
|
|
area and it may not be possible to program it as an MPU region.

This option directs standard output (e.g. printf) to the console
|
|
device, rather than suppressing it entirely. See also EARLY_CONSOLE
|

option.
