IMPORTANT
The use-prohibited output signals shown in Table 8.1 are accessed by the system
and cannot be accessed by the user.
In the event these signals are used (turned on/off) by the user, normal operations
cannot be guaranteed.
POINT
In the A/QnA series, data link startup was performed by setting the "Yn6 (Data Link
Startup Request initiated by a buffer memory parameter)" and "Yn8 (Data link
2
Startup Request initiated by an E PROM parameter)".
Do not use "Yn6" and "Yn8" for the Q series because the data link startup is
automatically performed.
