Appendix 4 Processing Time
Appendix 4.2 Factors that increase scan time
(c) When auto refresh is executed by another CPU module during auto refresh
processing
The auto refresh time increases by the time obtained by the following calculation.
• For the Basic model QCPU
Use the following value for N6.
• For the High Performance model QCPU, Process CPU, and Universal model QCPU
Use the following value for N5.
