7-6 Application Specific Instructions
Applications Requiring More than 16 Bits
When your application requires more than 16 bits, use parallel multiple
sequencer instructions.
Sequencer Output (SQO)
Sequencer Compare (SQC)
These instructions transfer 16-bit data to word addresses for the control of
sequential machine operations.
Enter Parameters
Enter the following parameters when programming these instructions.
• File is the address of the sequencer file. You must use the file indicator
(#) for this address.
• Mask (SQO, SQC) is a hexadecimal code or the address of the mask
word or file through which the instruction moves data. Set mask bits to
pass data and reset mask bits to mask data. Use a mask word or file if
you want to change the mask according to application requirements.
If the mask is a file, its length will be equal to the length of the
sequencer file. The two files track automatically.
• Source is the address of the input word or file for a SQC from which
the instruction obtains data for comparison to its sequencer file.
• Destination is the address of the output word or file for a SQO to
which the instruction moves data from its sequencer file.
TIP
If a String element address is used for the file
parameter, the maximum length for SLC 5/03 and
higher processors is 41 words. Additionally, String
element boundaries cannot be crossed.
