To store a second program, repeat this process.
The procedure for writing these settings to the EEPROM is described in the 7th example on
40...42.
Replacing the EEPROM is described on 59 for BIS C-6002 and on 71 for BIS C-6022.

Function Description
Monitoring initialization, splitting memory
Command identifier 09
Hex
allows initialization data to be stored in the processor.
If the Monitor Data carrier Initialization function is activated, a read/write command results first
in the initialization data on the data carrier being compared with the data in the processor. If
these do not agree, error message 17
Hex
is output. If the data carrier has not even been initial-
ized yet, i.e. all initialization data are 0, error message 18
Hex
is output.
Command identifier 0A
Hex
allows an address to be stored in the processor starting at which
the data carrier 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 9 for calculation).
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 data carrier entering the
read/write zone of the processor.
