(c) When auto refresh of another CPU occurs during auto refresh processing of a CPU
If auto refresh of another CPU occurs during auto refresh processing of a CPU, the auto refresh time increases
by the time obtained from each the following calculations.
1) For Basic model QCPU
(Extension time) = 4
Use the values in Table5.7 for N6
Table5.7 Time prolonged when processing of other CPU is duplicated
Basic model QCPU
Q00CPU
Q01CPU
2) For High Performance model QCPU/Process CPU
(Extension time) = (No. of transmission/reception word points)
Use the values in Table5.8 for N5
