Description

Functions for the level-1 instruction cache.

Function Documentation

__STATIC_FORCEINLINE void SCB_DisableICache ( void )

Disable I-Cache.

The function turns off the instruction cache.

__STATIC_FORCEINLINE void SCB_EnableICache ( void )

Enable I-Cache.

The function turns on the instruction cache.

Note: Before enabling the instruction cache, you must invalidate (SCB_InvalidateICache) the entire instruction cache if external memory might have changed since the cache was disabled.; After reset, you must invalidate (SCB_InvalidateICache) each cache before enabling it.

__STATIC_FORCEINLINE void SCB_InvalidateICache ( void )

Invalidate I-Cache.

The function invalidates the instruction cache. The instruction cache is never dirty so cache RAM errors are always recoverable by invalidating the cache and retrying the instruction.

Note: After reset, you must invalidate each cache before enabling (SCB_EnableICache) it.

__STATIC_FORCEINLINE void SCB_InvalidateICache_by_Addr	(	void *	addr,
		int32_t	isize
	)

I-Cache Invalidate by address.

Invalidates I-Cache for the given address. I-Cache is invalidated starting from a 32 byte aligned address in 32 byte granularity. I-Cache memory blocks which are part of given address + given size are invalidated.

Parameters

[in]	addr	address
[in]	isize	size of memory block (in number of bytes)
