As the above figure, there are three branch circuit

which
① ，
is circuit block
②
in series; when there is the serial circuit block in the parallel from the
bus to node or between nodes, the following branch end uses RD instruction except for the first
branch. The branch is not serial circuit block to use OR instruction.
③
OR.STK and AND.STK are instructions without operation components, indicating the OR, AND
relationship between circuit blocks.

Instruction and function
Instruction Function
AND.STK
Sets the logical product of ST0 and ST1, and shifts the
stack register right by one bit.
Instruction specification
z When the branch loop (parallel loop block) is connected to the previous loop in series, use
AND.STK instruction. The starting point of branch uses RD, RD.NOT instruction, after the
parallel loop block ends, AND,STK instruction is connected to previous loop in series.
z AND.STK a sole instruction without other address.
