cacheSh7040LibInit( )

NAME

cacheSh7040LibInit( ) - initialize the SH7040 cache library

SYNOPSIS

STATUS cacheSh7040LibInit
    (
    CACHE_MODE instMode, /* instruction cache mode */
    CACHE_MODE dataMode  /* data cache mode (ignored) */
    )

DESCRIPTION

This routine initializes the cache library for the Hitachi SH7040 processors. It initializes the function pointers and configures the caches to the specified cache modes. Modes should be set before caching is enabled. If two complementary flags are set (enable/disable), no action is taken for any of the input flags.

Next caching modes are available for the SH7040 processors:

	SH7040:	CACHE_WRITETHROUGH	(cache for instruction)
		CACHE_SH7040_DRAM	(enable caching for DRAM space)
		CACHE_SH7040_CS3	(enable caching for CS3 space)
		CACHE_SH7040_CS2	(enable caching for CS2 space)
		CACHE_SH7040_CS1	(enable caching for CS1 space)
		CACHE_SH7040_CS0	(enable caching for CS0 space)

RETURNS

OK, or ERROR if the specified caching modes were invalid.
