Standard edge detection function blocks
Standard counter function blocks
Standard timer function blocks
The function and function block of the application functions execute the operation with the combination of
multiple sequence instructions. Therefore, if the interrupt occurs in the application function operations,
unintended operation results may occur.
For using an interrupt program, use Disable interrupt/ Enable interrupt (DI/EI instruction) as necessary.
