9 CREATING A HARDWARE LOGIC

• Multi function counter block detail window (Counter_1(32bit_Unsigned))
• Multi function counter block detail window (Counter_2(32bit_Unsigned))
• An SI device terminal linked in the hardware logic must be assigned to an interrupt pointer of the CPU
module. If an unassigned SI device terminal turns to High, an error occurs in the CPU module.
• An interrupt request to the CPU module can also be output using a detection in the input signal event
detection block as a trigger. The following figure shows a link example in the hardware logic outline window
and the multi function counter block detail window.
• For the linking of the multi function counter block detail window (Counter_0(16bit_Unsigned)), a value other
than 0 is recommended for "Compare Value". If 0 is set in "Compare Value", an interrupt request is output to
the CPU module when the operation of the hardware logic starts (when the count value starts to be counted
from 0).
An interrupt request to the CPU module is output every 50
μ
s.
If the same interrupt factor (SI) occurs several times within 50
μ
s, the second and later factors (SI) are ignored.
