IAS x: Interrupt Active Status
Indicate the status of the corresponding interrupt source
0 = Corresponding interrupt channel is inactive
1 = Corresponding interrupt channel is active
AIC Interrupt Status Register (AIC_ISR)
This register identifies those interrupt channels whose are both active and enabled.
ISx: Interrupt Status
Indicates the status of corresponding interrupt channel
0 = Two possibilities:
1 = Corresponding interrupt channel is both active and enabled (can assert an interrupt)
