ADuC7033
Remap Operation
SYSMAP0 Register
When a reset occurs on the ADuC7033, execution starts
automatically in the factory programmed internal configuration
code. This so-called kernel is hidden and cannot be accessed by
user code. If the ADuC7033 is in normal mode, it executes the
power-on configuration routine of the kernel and then jumps to
the reset vector, Address 0x00000000, to execute the user’s reset
exception routine. Because the Flash/EE memory is mirrored at
the bottom of the memory array at reset, the reset routine must
always be written in Flash/EE memory.
The remap command must be executed from the absolute
Flash/EE memory address, and not from the mirrored,

SRAM. If a remap operation is executed while operating code
from the mirrored location, prefetch/data aborts can occur or
