Description

Extract Longword Low shifts the register $s_reg1 right by 0-7 bytes, inserts zeros into the vacated bit positions, and then extracts the four low-order bytes and stores them in the destination register. The four 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.
