ANB
Outline
Use ANB instruction to connect a branch circuit (parallel circuit block) to the preceding circuit in series.
Use LD or LDI instruction at the start of branch. After completing a parallel circuit block, connect the parallel
circuit block to the preceding circuit in series by ANB instruction.
When there are many parallel circuits, ANB instruction can be used in each circuit block to connect them.

2. Applicable devices
Explanation of function and operation
1. ANB instruction (serial connection of multiple parallel circuits)
Caution
There is no limitation in the number of ANB instruction.
Though ANB instructions can be used at one time, note that the repeated use of LD or LDI instruction is
limited to 8 or less in the same way as ORB instruction.
