(c) When the destination is a word device
Instruction that processes 16-bit data
(d) When a digit is specified at the destination
When the source
X010
When the source
X010
(2) Using word devices
A word device is specified in unit of one point (16 bits).
4.4 Method for Specifying Data
4-24
4.4.2 Word (16 bits) data
For the word device at the destination side, 0s are stored to bits starting from the digit
specified at the source.

used for the start device number of bit devices.
2. Digits cannot be specified for direct access inputs/outputs (DX, DY).
