Description:
Move one word operand to/from Y memory. One effective address is specified. All memory addressing
modes, including absolute address and immediate data, may be used. Long displacement addressing
may also be used. A memory to register or register to memory direction may be specified.
If the opcode-operand portion of the instruction specifies as the destination a portion of the register Dn, the
same register portion may not be specified as a destination D in the data bus move operation. That is, du-
plicate destinations are not allowed in the same instruction. For example, both a Data ALU operation and
a data move operation cannot write into the same register in the same instruction.
If the opcode-operand portion of the instruction specifies as the source or destination a portion of the reg-
ister Dn, the same register portion may be specified as a source S in the data bus move operation. That is,
duplicate sources are allowed in the same instruction. For example, a data move operation can read the
same register which is being used as a source or destination by a Data ALU operation in the same instruc-
tion.
See restrictions in Section A.10.6 concerning Rn, Mn, and Nn registers as a
destination.
