In Normal/Secured Bootloader mode, once AAMR[3] has been set (i.e.-Nibble 0 is marked as valid), the

Shadow Block is no longer available at address $0000 0000. Any write to the AAMR that does not set bit

3 will leave the Shadow Block mirroring at address $0000 0000. As an example, in Normal/Secured

Bootloader mode, the initial AAMR register value is $f000 0b88. If the user writes $f000 0bb0 to the

AAMR register, the following configuration will be set:

However, if the user writes $f000 0bb8 to the AAMR register, the following configuration will be set:
