3.3
3.3.1
The SH-4 supports a 32-bit physical address space, and can access a 4-Gbyte address space. When
the MMUCR.AT bit is cleared to 0 and the MMU is disabled, the address space is this physical
address space. The physical address space is divided into a number of areas, as shown in figure
3.3. The physical address space is permanently mapped onto 29-bit external memory space; this
correspondence can be implemented by ignoring the upper 3 bits of the physical address space
addresses. In privileged mode, the 4-Gbyte space from the P0 area to the P4 area can be accessed.
In user mode, a 2-Gbyte space in the U0 area can be accessed. Accessing the P1 to P4 areas
(except the store queue area) in user mode will cause an address error.

MMU exceptions are not generated when the AT bit is 0. In the case of software that does not
use the MMU, therefore, the AT bit should be cleared to 0.
