Error Interrupt Configuration Registers, GICT_ERRIRQCR<n>

GICT_ERRIRQCR0 controls the fault handling interrupts. GICT_ERRIRQCR1 controls the error recovery interrupts.

The GICT_ERRIRQCR<n> characteristics are:

Usage constraintsIf GICD_SAC.GICTNS == 0, then only Secure software can access the functions of this register.
ConfigurationsAvailable in all GIC-600 configurations.
AttributesSee GICT register summary.

The following figure shows the bit assignments.

Figure 4-41 GICT_ERRIRQCR<n> bit assignments


The following table shows the bit assignments.

Table 4-54 GICT_ERRIRQCR<n> bit assignments

Bits Name Function
[31:10] - Reserved, RAZ.
[9:0] SPIID

SPI ID.

Returns 0 if an invalid entry is written.

In a multichip configuration, the SPIID field must only be programmed to an SPI ID that the chip owns. The relevant GICD_CHIPRn register controls the SPI ownership.

Arm® recommends that if these registers are used, then the SPI must not be used for another device either with a wire or as a message-based interrupt.
