Register Array Variables
i,j,k,l,m,nWhen these variables are used in a register name, an offset, or an address, they refer to the value of a register array where the register is part of a group of repeating registers. The register groups form a hierarchical structure and the array is represented with a formula.
yWhen this variable is used in a register name, an offset, or an address it refers to the value of a register array.

14.3.7 IIDX (Offset = 1020h) [Reset = 00000000h]

IIDX is shown in Figure 14-12 and described in Table 14-18.

Return to the Summary Table.

This register provides the highest priority enabled interrupt index. 0x0 means no event pending. Interrupt 1 is the highest priority, 2 next highest, 4, 8, … 231 is the least priority. That is, the least bit position that is set to 1 denotes the highest priority pending interrupt. The priority order is fixed. However, users can implement their own prioritization schemes using other registers that expose the full set of interrupts that have occurred.

On each read, only one interrupt is indicated. On a read, the current interrupt (highest priority) is automatically cleared by the hardware and the corresponding interrupt flag in the RIS and MIS are cleared as well. After a read from the CPU (not from the debug interface), the register must be updated with the next highest priority interrupt, if none are pending, then it should display 0x0.

14.3.13 IIDX (Offset = 1050h) [Reset = 00000000h]

IIDX is shown in Figure 14-18 and described in Table 14-24.

Return to the Summary Table.

This register provides the highest priority enabled interrupt index. 0x0 means no event pending. Interrupt 1 is the highest priority, 2 next highest, 4, 8, … 231 is the least priority. That is, the least bit position that is set to 1 denotes the highest priority pending interrupt. The priority order is fixed. However, users can implement their own prioritization schemes using other registers that expose the full set of interrupts that have occurred.

On each read, only one interrupt is indicated. On a read, the current interrupt (highest priority) is automatically cleared by the hardware and the corresponding interrupt flag in the RIS and MIS are cleared as well. After a read from the CPU (not from the debug interface), the register must be updated with the next highest priority interrupt, if none are pending, then it should display 0x0.

IIDX is shown in Figure 14-24 and described in Table 14-30.

Return to the Summary Table.

This register provides the highest priority enabled interrupt index. 0x0 means no event pending. Interrupt 1 is the highest priority, 2 next highest, 4, 8, … 231 is the least priority. That is, the least bit position that is set to 1 denotes the highest priority pending interrupt. The priority order is fixed. However, users can implement their own prioritization schemes using other registers that expose the full set of interrupts that have occurred.

On each read, only one interrupt is indicated. On a read, the current interrupt (highest priority) is automatically cleared by the hardware and the corresponding interrupt flag in the RIS and MIS are cleared as well. After a read from the CPU (not from the debug interface), the register must be updated with the next highest priority interrupt, if none are pending, then it should display 0x0.
