User manual
5.6.9 Interrupt Active Bit Register 0
The IABR0 register is a read-only register that allows reading the active state of the first
32 peripheral interrupts. This allows determining which peripherals are asserting an
interrupt to the NVIC, and may also be pending if there are enabled. The remaining
interrupts can have their active state read via the IABR1 register
The bit description is as follows for all bits in this register:
Write — n/a.
Read — 0 indicates that the interrupt is not active, 1 indicates that the interrupt is active.
