Hi. In table 3.16 on page 24 is probably error. In D template is only 3bit length field OP1, so OP can't be 0-15, but just only 0-7 in "1.5 D".
Same problem is in table 3.17. Unconditional jump/call has OPJ=0-7 and 8-15 in 3bit field. ???

And another question: How do you discriminate between jump instructions in format 1.5C and 1.5D format?
IL and Mode fields are same. And if whole 3bit OP1 field in 1.5D format was used, there are no other bits for different encoding 1.5C!
