Assembler Syntax

AE_SBF a0..15(ars)

C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern void AE_SBF(unsigned short * a /*inout*/);

Description

AE_SBF flushes any remaining bits from AE_BITHEAD to the stream in memory pointed to by (a + 2). After the instruction executes, the number of data bits stored (as opposed to padding) can be retrieved from the AE_BITPTR state register.
