Table 15: Markers and analog operands
Avoid any accidental double assignment of markers. In this way, you can
assign the available 96 or 128 marker bit contacts and also change the state
of these marker bits via the first 12 marker bytes (MB), 6 marker words or 3
marker double words. This will generate undefined states. When write
accesses are made successively within an MD, such as to MD1, MW2, MB4
or M32, the last write operation is retained.

Tip: Observing the following wiring rules will prevent the double
assignment of marker bits.
•
For easy800 standard with the marker bits M01-M96 use
•
Marker bytes, starting at MB13
•
Marker words, starting at MW07
•
Marker double words, starting at MD04
•
For easy800-SWD with the marker bits M01-M128 use
•
Marker bytes, starting at MB13
•
Marker words, starting at MW07
•
Marker double words starting at MD04
