Bit x = 0
If more than 1 function is activated, then the following applies:
•
The values for all functions cannot be read until each activated function has
terminated and this has been confirmed in the corresponding status bit
(ZSW.0/.1/.2/.3 "0" signal again).
Reference mark search
•
It is possible to search for a reference mark.
External zero mark
•
