2) When is a word device (1 ≤ n ≤ 4)
ON bit positions among "2
n
" bits (1 ≤ n ≤ 4) from a device specified in are encoded to .
-The encoding result of is "0" (OFF) from the most significant bit to the low-order bit "n".
Cautions
1. When two or more bits are ON in the data
The low-order side is ignored, and only the ON position on the high-order side is encoded.
2. While the command input is OFF
The instruction is not executed. Activated encode outputs are latched in the previous ON/OFF status.
