Assembler Syntax

AE_SA24X2.IC aed0..15(ae_ls_v), u0..3(ae_ls_su), a0..15(ars)

C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern void AE_SA24X2_IC(ae_int24x2 d, ae_valign su /*inout*/, void * a /*inout*/);

Description

AE_SA24X2.IC stores the low 24-bits from each half of the AE_DR register d, packed into memory, meaning that it occupies only 48-bits in memory. It forms a virtual address using the address register.

Note: the .IC suffix indicates that the operation is using a circular buffer addressing mode. The updated base address is formed by adding 6 to the base address with circular wrap-around.
