#define __putbit	(		value,
			address,
			bitoffset
	)		__imaskldmst(address,value,bitoffset,1)

Store a single bit.

Function Documentation

sint32 __extr	(	sint32	,
		uint32	,
		const uint32
	)

Extract a bit-field (bit pos to bit pos+width) from value

uint32 __extru	(	uint32	,
		uint32	,
		const uint32
	)

Same as __extr() but return bit-field as unsigned integer

asm volatile void __imaskldmst	(	uint32 *	a,
		sint32	b,
		sint32	p,
		const sint32	w
	)

Atomic load-modify-store.

Definition at line 338 of file IfxCpu_IntrinsicsDcc.h.

uint32 __ins	(	uint32	,
		const uint32	,
		uint32	,
		const uint32
	)

Return trg but replace trgbit by srcbit in src.

uint32 __insert	(	uint32	,
		uint32	,
		uint32	,
		const uint32
	)

Extract bit-field (width w bits starting at bit 0) from a and insert it in b at position p.

uint32 __insn	(	uint32	,
		const uint32	,
		uint32	,
		const uint32
	)

Return trg but replace trgbit by inverse of srcbit in src.
