6 BASIC INSTRUCTIONS
6.5 Data Conversion Instructions
Decoding from 8 to 256 bits
DECO(P)
These instructions decode the lower-order (n) bits of the device specified by (s), and store the result in the 2 (to the power (n))
bit from the device specified by (d).

Processing details
• These instructions turn ON the bit position of the device specified by (d) in correspondence to the BIN value specified by
the lower-order (n) bits of (s).
• 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.
