ARM Cortex-A76 Core User Manual

0 Disables use of ICC_PMR as a hint for interrupt distribution.
1 Enables use of ICC_PMR as a hint for interrupt distribution.
RES0, [5:2]
Reserved, RES0.
EOImode, [1]
End of interrupt mode for the current security state. The possible values are:
0 ICC_EOIR0 and ICC_EOIR1 provide both priority drop and interrupt deactivation
functionality. Accesses to ICC_DIR are UNPREDICTABLE.
1 ICC_EOIR0 and ICC_EOIR1 provide priority drop functionality only. ICC_DIR
provides interrupt deactivation functionality.
CBPR, [0]
Common Binary Point Register. Control whether the same register is used for interrupt
preemption of both Group 0 and Group 1 interrupt. The possible values are:
0 ICC_BPR0 determines the preemption group for Group 0 interrupts.
ICC_BPR1 determines the preemption group for Group 1 interrupts.
1 ICC_BPR0 determines the preemption group for Group 0 and Group 1 interrupts.
