AIC Interrupt Source Number Register (AIC_ISNR)
The purpose of this register is to record the interrupt channel number that is active, enabled, and has the
highest priority.
IRQID [4:0]: IRQ Identification
Stands for the interrupt channel number
AIC Interrupt Mask Register (AIC_IMR)
IM x: Interrupt Mask
This bit determines whether the corresponding interrupt channel is enabled or disabled. Every
interrupt channel can be active no matter whether it is enabled or disabled. If an interrupt channel is
enabled, it does not definitely mean it is active. Every interrupt channel can be authorized by the AIC
only when it is both active and enabled.
