2.7.1.7 Interrupt Active Bit Registers

The NVIC_IABR0-NVIC_IABR7 registers indicate which interrupts are active. See the register summary in Table 2-34 for the register attributes.

The bit assignments are:

Figure 2-23. IABR Register Bit Assignments

Table 2-40. NVIC_IABR Bit Assignments
Bits	Name	Function
[31:0]	ACTIVE	Interrupt active flags: 0: interrupt not active 1: interrupt active.

A bit reads as one if the status of the corresponding interrupt is active or active and pending.
