(Continued)
Y1 : Usable
Y2 : Usable, with EI2OS stop function
N : Unusable
Notes :
The peripheral resources sharing the ICR register have the same interrupt level.
When two peripheral resources share the ICR register, only one can use Extended Intelligent I/O Service
at a time.
When either of the two peripheral resources sharing the ICR register specifies Extended Intelligent I/O
Service, the other one cannot use interrupts.
