Extract Byte Low (extbl)

Syntax

extbl $s_reg1, $s_reg2, $d_reg

extbl $d_reg/$s_reg1, $s_reg2

extbl $s_reg1, val_immed, $d_reg

extbl $d_reg/$s_reg1, val_immed

Description

Extract Byte Low shifts the register $s_reg1 right by 0-7 bytes, inserts zeros into the vacated bit positions, and then extracts the low-order byte into the destination register. The seven high-order bytes of the destination register are cleared to zeros. Bits 0-2 of register $s_reg2 or the immediate value specifies the byte shift count.
