1.1 Purpose

Prepare the functions and cache register operation function format macros required after DMA execution.

1.2 Overview

The main use of this library is to provide a cache purge function to call after a DMA transfer.
When the CPU accesses RAM in the memory space using a cache address, if a DMA transfer is performed with that RAM as the destination, an inconsistency will occur between the contents of the RAM and the cache. In such cases, you need to purge the cache. For more information about caching, please see the SH2 hardware manual.
