and 64 bytes, so the address ranges 0x0180–0x047F and 0x08C0–0x097F are considered reserved space.
When it is configured with 32 MBs, the memory sizes are 544 and 128 bytes, so the address ranges
0x0280–0x047F and 0x0900–0x097F are considered reserved space. Furthermore, if the BCC bit in MCR
is negated, then the whole Rx Individual Mask Registers address range (0x0880–0x097F) is considered
reserved space.
