CPU MODULE PROCESSING TIME

11.1.3 Factors that increase the scan time

When the following functions or operations are performed, this will increase the scan time
of the CPU module.
When executing any of them, make sure to allow for the processing time (the value given
in this section to the value calculated in Section 11.1.2).

When sampling trace (
shown in Table11.19 will be required.
registers (word devices) are set as sampling trace data
Note10
Since the Basic model QCPU cannot use sampling trace, it is not necessary to be conscious of
the sampling trace processing time.
