User callable simple cache clearing (V37)
SYNOPSIS
CacheClearU()
void CacheClearU(void);
void CacheClearU(void);
FUNCTION
Flush out the contents of any CPU instruction and data caches. If dirty data cache lines are present, push them to memory first.
Caches must be cleared after *any* operation that could cause invalid or stale data. The most common cases are DMA and modifying instructions using the processor. See the CacheClearE() autodoc for a more complete description.
Some examples of when the cache needs clearing: - Self modifying code - Building Jump tables - Run-time code patches - Relocating code for use at different addresses. - Loading code from disk
