7.3.2 Conversion from QnASCPU to QCPU

This section explains the parameter conversion upon replacement of the QnASCPU program with the
QCPU.
The symbols in the table indicate the following meanings:
<Compatibility>
: Common item between QnASCPU and QCPU, therefore can be converted directly
: Item that requires re-setting after the conversion, since the functions/specifications are partially
different
: Item to be deleted, since there is no common item between the QnASCPU and QCPU
Confirm the parameters after the conversion, and correct/re-set as required.
