Modes should be set before caching is enabled.If two complementary flags are set (enable/disable), no action is takenfor any of the input flags.<p>Next caching modes are available for the SH7040 processors:<p><table><tr valign=top><td align=left></td><td align=left> SH7040:</td><td align=left> <b>CACHE_WRITETHROUGH</b> </td><td align=left> (cache for instruction)</tr><tr valign=top><td align=left></td><td align=left> </td><td align=left> <b>CACHE_SH7040_DRAM</b> </td><td align=left> (enable caching for DRAM space)</tr><tr valign=top><td align=left></td><td align=left> </td><td align=left> <b>CACHE_SH7040_CS3</b> </td><td align=left> (enable caching for CS3 space)</tr><tr valign=top><td align=left></td><td align=left> </td><td align=left> <b>CACHE_SH7040_CS2</b> </td><td align=left> (enable caching for CS2 space)</tr><tr valign=top><td align=left></td><td align=left> </td><td align=left> <b>CACHE_SH7040_CS1</b> </td><td align=left> (enable caching for CS1 space)</tr><tr valign=top><td align=left></td><td align=left> </td><td align=left> <b>CACHE_SH7040_CS0</b> </td><td align=left> (enable caching for CS0 space)</tr><tr valign=top><td align=left></tr></tr></table></blockquote><h4>RETURNS</h4><blockquote><p>OK, or ERROR if the specified caching modes were invalid.</blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./cacheSh7040Lib.html#top">cacheSh7040Lib</a></b></body></html>⌨️ 快捷键说明
