1)
  The same channel cannot be used by more than one function. 
2)
 
The inputs and outputs cannot be allocated to more than one function. 
Inputs and outputs that have been allocated to a high-speed counter or pulse output function cannot be used 
as normal inputs or outputs. 
X0–X5 can also be used as pulse catch inputs or interrupt inputs.
