Remap Operation
When a reset occurs on the ADuC7036, 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 ADuC7036 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 reset
exception routine of the user. Because the Flash/EE is mirrored at
the bottom of the memory array at reset, the reset routine must
always be written in Flash/EE.
The remap command must be executed from the absolute
Flash/EE address and not from the mirrored, remapped
segment of memory, which may be replaced by SRAM. If a
remap operation is executed while operating code from the
mirrored location, prefetch/data aborts may occur or the user
may observe abnormal program operation.
Any kind of reset remaps the Flash/EE memory to the bottom
of the memory array.

SYSMAP0 Register
Name: SYSMAP0
Address: 0xFFFF0220
Default Value: Updated by the kernel
Access: Read/write access
Function: This 8-bit register allows user code to remap either
RAM or Flash/EE space into the bottom of the ARM memory
space, starting at Address 0x00000000.

Bit
7 to 1
0
Description
Reserved. These bits are reserved and should be written
as 0 by user code.
Remap bit.
Set by the user to remap the SRAM to 0x00000000.
Cleared automatically after a reset to remap the
Flash/EE memory to 0x00000000.
