There is a 64-Kbyte mixed instructionand data cache that operates in write-through or copyback mode. Eachcache line contains 32 bytes. Cache tag operations are performed with"line," "page," "segment," or "region" granularity.<p>MMU (Memory Management Unit) support is needed to mark pages cacheableor non-cacheable. For more information, see the manual entry for vmLib.<p>For general information about caching, see the manual entry for cacheLib.<p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><b>cacheLib.h</b><p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./cacheCy604Lib.html#top">cacheCy604Lib</a></b>, <b><a href="./cacheLib.html#top">cacheLib</a></b>, <b><a href="./vmLib.html#top">vmLib</a></b><hr><a name="cacheCy604LibInit"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>cacheCy604LibInit</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>cacheCy604LibInit</i>( )</strong> - initialize the Cypress CY7C604 cache library</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS cacheCy604LibInit ( CACHE_MODE instMode, /* instruction cache mode */ CACHE_MODE dataMode /* data cache mode */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine initializes the function pointers for the Cypress CY7C604cache library.
