7.3.5 Write-Back 

Buffer 

When the U bit of the entry to be replaced in the write-back mode is 1, it must be written back to 
the external memory. To increase performance, the entry to be replaced is first transferred to the 
write-back buffer and fetching of new entries to the cache takes priority over writing back to the 
external memory. After the cache completes to fetch the new entry, the write-back buffer writes 
the entry back to external memory. During the write-back cycles, the cache can be accessed. The 
write-back buffer can hold one line of cache data (16 bytes) and its physical address. Figure 7.3 
shows the configuration of the write-back buffer.

7.3.6 

Coherency of Cache and External Memory 

Use software to ensure coherency between the cache and the external memory. When memory 
shared by this LSI and another device is mapped in the address space to be cached, operate the 
memory mapped cache to invalidate and write back as required.
