Notes 1. Of the two mnemonics, either one of them or both can be written.
2. After transfer, modification specified by mod is performed.
3. Select any of dest, dest’ = {ro, reh, re, rh, rl}, source, source’ = {re, rh, rl}.
4. Select any of dest = {ro, reh, re, rh, rl}, source = {re, rh, rl}, addr = 0: X-0xFFF : X (X memory) .
0: Y-0xFFFF: Y (Y memory)
5. Select any of dest = {ro, reh, re, rh, rl}, source = {re, rh, rl}.
6. Select any register other than general-purpose registers as dest and source.
