Control and status bytes

Control and status byte of the first channel (L1)
Process data mode
Control byte 1 in process data mode
Control byte 1 (CB1) is located in the output image [} 46], and is transmitted from the controller to the
KL3403. Note the assignment of the control bytes to the process input data words.
