Sequencer Instructions
243
Addressing Modes and File Types can be used as shown in the following
table:
SQO- Sequencer Output
Instruction Type: output
On a false-to-true rung transition, the SQO instruction transfers masked
source reference words or long words to the destination for the control of
sequential machine operations. When the rung goes from false-to-true, the
instruction increments to the next step (word) in the sequencer file. Data
stored there is transferred through a mask to the destination address
specified in the instruction. Data is written to the destination word every
time the instruction is executed.
The done bit is set when the last word of the sequencer file is transferred.
On the next false-to-true rung transition, the instruction resets the position
to step one.
