3. Memory Management Unit (MMU)
CHCRn.DSAn, CHCRn.STC, and CHCRn.DTC values. For details, see section 14, Direct
Memory Access Controller (DMAC).
P0, P1, P3, U0 Areas: The P0, P1, P3, and U0 areas can be accessed using the cache. Whether or
not the cache is used is determined by the cache control register (CCR). When the cache is used,
with the exception of the P1 area, switching between the copy-back method and the write-through
method for write accesses is specified by the CCR.WT bit. For the P1 area, switching is specified
by the CCR.CB bit. Zeroizing the upper 3 bits of an address in these areas gives the corresponding
external memory space address. However, since area 7 in the external memory space is a reserved
area, a reserved area also appears in these areas.
P2 Area: The P2 area cannot be accessed using the cache. In the P2 area, zeroizing the upper 3
bits of an address gives the corresponding external memory space address. However, since area 7
in the external memory space is a reserved area, a reserved area also appears in this area.
P4 Area: The P4 area is mapped onto SH-4 on-chip I/O channels. This area cannot be accessed
using the cache. The P4 area is shown in detail in figure 3.4.
