Programmable key numbers and the datafill
The 22 feature keys available on the M522 add-on module are assigned key
numbers to enable the switch to identify individual key functions. The
numbering scheme used for key assignments is shown in Figure 3-1.
The presence of the M522 is transparent to the process of data filling the
M5216/M5316 set.
