Function Description
Monitoring initialization, splitting memory
Command identifier 09 allows initialization data to be stored in the processor.
Hex
If the Monitor Code Tag Initialization function is activated, a read/write command results first
in the initialization data on the code tag being compared with the data in the processor. If
these do not agree, error message 17
yet, i.e. all initialization data are 0, error message 18
Command identifier 0AHex allows an address to be stored in the processor starting at which
the code tag data are no longer memory-optimized.
When dividing the memory, make the sector with memory optimization large enough so that it
is sufficient for the maximum intended number of write cycles (see
Division brings an advantage in processing small quantities of data that are frequently pro-
grammed (written) in the sector not having memory optimization.
If the split function is activated, this memory division applies to every code tag entering the
read/write zone of the processor.
