4.3.3
The Interrupt Request Level Register (IRLR) is an 8-bit read-only register that holds the
interrupt level (obtained from an interrupt level field (ILRn, n=0 - 31) in the Interrupt Level
Control Registers 0 to 15 (ILCONn, n=0 - 15)) for the unmasked interrupt request with the
highest priority.
After a system reset, it contains 0x00.
IRL
This field holds the interrupt level assigned to the unmasked interrupt request with the highest
priority. The interrupt controller obtains this level, a number between 1 and 7, from the
interrupt level field (ILRn, n=0 - 31) in the Interrupt Level Control Registers 0 to 15 (ILCONn,
n=0 - 15) corresponding to the source of the interrupt request.
