Section 2 CPU
(5)
The P4 area is defined as a control area which is non-cacheable and non-address translatable. This
area can be accessed only in privileged mode. A part of the LSI’s on-chip I/O is assigned to this
area.
Table 2.1
2.2.2
This LSI uses 29 bits of the 32-bit virtual address to access external memory. In this case, 0.5-
Gbyte of external memory space can be accessed. The external memory space is managed in area
units. Different types of memory can be connected to each area, as shown in figure 2.2. For
details, please refer to section 9, Bus State Controller (BSC).
In addition, area 1 in the external memory space is used as an on-chip I/O space where most of
this LSI’s on-chip I/Os are mapped.
Normally, the upper three bits of the 32-bit virtual address are masked and the lower 29 bits are
used for external memory addresses.*
H'80000100 in the P1 area, address H'A0000100 in the P2 area, and address H'C0000100 in the P3
area of the virtual address space are mapped into address H'00000100 of area 0 in the external
memory space. The P4 area in the virtual address space is not mapped into the external memory
address. If an address in the P4 area is accessed, an external memory cannot be accessed.
