Table 1. Interrupt Registers
Address Name RW Default Value Description
0x10 ISR RW 0x00000000 Interrupt status and clear. Each bit indicates if an error condition has occurred.

If a Status bit is 1 and the corresponding Mask bit is 0, then the interrupt signal is asserted.

Write 1 to a Status bit to clear it. Writes of value 0 have no effect.
0x14 IMR RO 0x0000003F Interrupt mask.

For each bit:

  • 0: Interrupt is enabled.
  • 1: Interrupt is masked (disabled).

If an ISR bit is 1 and the corresponding IMR bit is 0, then the interrupt signal is asserted.

Read only. Use the IEN and IDS registers to change the mask.
0x18 IEN WO n/a Interrupt enable.

Write 1 to a bit to enable the corresponding interrupt (set corresponding mask bit to 0).

Writes of value 0 have no effect.

Reads as zero.
0x1C IDS WO n/a Interrupt disable.

Write 1 to a bit to disable the corresponding interrupt (set corresponding mask bit to 1).

Writes of value 0 have no effect.

Reads as zero.

Fields for each interrupt register are the same:

Table 2. Interrupt Register Fields
Field Name Bits RW Notes
MID_MISS 0 Varies Manager ID miss. The transaction’s SMID, after masking is applied, does not match any manager ID in the manager ID list.
MID_RO 1 Varies Manager ID read-only violation. The manager attempted a write, but a manager ID list entry matching the request specifies read-only permission.
SEG_RD_MISS 2 Varies Address segment read miss. A read transaction’s address does not match any address segment in the address segments list, and default read access is not permitted (see CTRL_STATUS: DEF_RD).
SEG_WR_MISS 3 Varies Address segment write miss. A write transaction’s address does not match any address segment in the address segments list, and default write access is not permitted (see CTRL_STATUS: DEF_WR).
SEG_MID 4 Varies Address segment manager ID access violation.

The transaction manager ID is not permitted to access the address segment containing the transaction address.
SEG_TZ 5 Varies Address segment TrustZone security violation. A non-secure transaction attempted to access a secure address segment.
