LD.D
Load Double-word
Description
Load the double-word contents of the memory location specified by the addressing mode into the extended data
register E[a]. The least-significant word of the double-word value is loaded into the even register (D[n]) and the
most-significant word is loaded into the odd register (D[n+1]).

EA = {off18[17:14], 14b'0, off18[13:0]};

EA = A[b] + sign_ext(off10);
E[a] = M(EA, doubleword);
