EXG | 1E | Implied | In extension to the normal exchange of Byte and Word registers also
exchange of mixed Byte/Word registers is supported. If the target is a
Word the upper Byte is filled with $FF. If the target is a Byte only
the lower Byte of the source register is moved. Also supports "invalid" register codes. If the source is such an invalid register $FF or $FFFF is moved to the target register |
TFR | 1F | Implied | In extension to the normal transfer of Byte and Word registers also
