(d) Overhead time when local devices in the interrupt program are enabled
When SM777 (Enable/disable local device in interrupt program) turns on, the time given in the following tables
will be added to the overhead time given in Page 468, Appendix 3.2 (3) (a). Each n, N1, N2, and N3 in the table
indicates the following.
• n: Number of local device points (unit: K words)
• N1: Number of devices that specified a local device
• N2: Number of word device points that specified a local device
• N3: Number of bit device points that specified a local device
