LD.W – Load Word
Architecture revision:
Architecture revision1 and higher.
Description
Format I to V: Reads the word memory location specified.
Format VI: This instruction extracts a specified byte from Ri. This value is zero-extended, shifted
left two positions and added to Rb to form an address. The contents of this address is loaded
into Rd. The instruction is useful for indexing tables.
