Specific interrupt for one event

Hello,

This is a mistake in the library.
We will fix the bug and update ioLibrary.
Please refer to code. Thank you.
But if you use two or more interrupt, Do not use this function.
When two interrupts are asserted at the same time, only one interrupt be processed.

for(ir=0; ir<8; ir++){ 
   if(sir & (0x01 <<ir) ) setSn_IR(ir, 0xff); 
} 

Thank you.
