Processing details
• These instructions store into (d) the binary value corresponding to the bit whose value is 1 in the data with 2
8 7 6 5 4 3 2 1 0
(s)
0 0 1 0 0 0 0 0 0
• When (n) is 0, no processing is performed, and the contents of the device specified by (d) do not change.
• The bit device is handled as a device storing one-bit data and the word device is handled as a device storing 16-bit data.
• If two or more bits are 1, the higher bit position is processed.
Operation error
