When the file register is specified in the serial access format (ZR
access instruction to the standard RAM on the High Performance model QCPU of
which first 5 digits of serial No. are 02092 or later, the processing time per
instruction becomes longer than that of the High Performance model QCPU of
02091 or earlier. (The increased time per instruction is 1.1 s for the Q02CPU and
0.65 s for the QnHCPU on average.)
Table9.14 indicates the processing time taken when the MOV instruction is used.
