You enable the respective parameter by setting the associated bit to 1.
1)
Reserved bits must be set to 0.
2)
In isochronous mode, the parameter can have an effect on the isochronous parameters of the Sync domain. Because
3)
the isochronous parameters are not checked in RUN, overflows can occur. You prevent overflows by selecting the op-
tion with the greatest time demand during offline parameter assignment.
Note
DQ functions
You can select the "Between comparison value 0 and 1" function only for digital output DQ1
and only if you have selected the "Use by user program" function for digital output DQ0.
