In the following example when X1 is on, the value formed by discrete locations X10–X14 is
loaded into the accumulator using the Load Formatted instruction. The 5- bit binary pattern in
the accumulator is decoded by setting the corresponding bit position to a “1” using the Decode
instruction.

Decode (DECO)
The Decode instruction decodes a 5-bit binary value of 0–31
(0–1Fh) in the accumulator by setting the appropriate bit
position to a 1. If the accumulator contains the value Fh (HEX),
bit 15 will be set in the accumulator. If the value to be decoded
is greater than 31, the number is divided by 32 until the value is
less than 32 and then the value is decoded.
