2) When is a word device (1 ≤ n ≤ 4)
The numeric value (expressed in 2
n
on the low-order side) of is decoded to .
-When all bits of are "0", b0 of the word device turns ON.
-In the case of "n ≤ 3", all of high-order bits of become "0" (turn OFF).
Caution
• While the command input is OFF, the instruction is not executed. The activated decode output is held in the
previous ON/OFF status.
• When "n" is "0", the instruction executes no processing.
