9. INTERFACE MODE
9.6 Interrupt output cycle
When several buffer are used in interrupt valid, and interrupt output for every control cycle is not needed, the
cycle of interrupt output can be changed by the interrupt output cycle of Interface mode option (parameter
No.000F).

Interrupt output cycle
When interrupt by interface mode
is valid, set the cycle for which
the interrupt is output.
Interrupt output cycle:
Control cycle (setting value+1)
Example: When interrupt output cycle
is set to 1 and control cycle
is 0.88ms, interrupt is output
approximately every 1.77ms.
