INTERRUPT CONTROLLER S3C2416X RISC MICROPROCESSOR
The interrupt controller has two groups of interrupt sources, and first group has always higher priority than the
other group. Actually, we made this interrupt controller using by two interrupt controllers. The nRIQ of ARM926EJ
is connected with 'AND' of nIRQs of each interrupt controller. The nFIQ is just same.
