The two tables are showing the part of the memory, mapped in bits, where the handshake flags are located.

m - Address assigned to the master module by the station number setting. This defines the memory area dedicated for this slave. It begins at address m of the master.

n - It depends on the number of occupied stations and the extended cyclic setting, as shown in the table:
