Register Name:
Access Type:
• IRR: Interrupt Request line
0 = No interrupt request is pending on this input request input.
1 = An interrupt request is pending on this input request input.
The are 64 IRRs, one for each group. Each IRR has 32 bits, one for each possible interrupt request, for a total of 2048 pos-
sible input lines. The IRRs are read by the software interrupt handler in order to determine which interrupt request is
pending. The IRRs are sampled continuously, and are read-only.
