Decoder
Decoder
The Decoder instruction sets the specified bit to TRUE and the other bits to FALSE in array elements
that consist of a maximum of 256 bits.
OLL
The Decoder instruction converts array elements with 2
Size
bits that start from InOut[0] in array to con-
vert InOut[]. It sets the specified bit to TRUE. It sets the other bits to FALSE. The bit to make TRUE is
specified by the Size bits in the lower byte of conversion bit position In. Always attach the element num-
ber to the in-out parameter that is passed to InOut[], e.g., array[3].
Consider an example where In is BYTE#16#09, Size is USINT#4, and InOut[] is a BYTE array. The
value of the Size bits in the lower bits of In is 16#9, which is 9 decimal. Therefore, the ninth bit from the
least-significant bit of InOut[] is made TRUE and the other bits are made FALSE.
