RBFM / Divided BFM Read
Outline
This instruction reads data from continuous buffer memories (BFM) in a special function block and unit over
several operation cycles by the time division method. This instruction is convenient for reading received data,
etc. stored in buffer memories in a special function block and unit for communication by the time division
method. FROM instruction is also available to read the buffer memory (BFM) data.
