MCU_IRQ
MCU IRQ Source Register
The MCU_IRQ collects all the interrupts from the peripherals and generates the
synchronous interrupt to Cortex
®
-M0. There are two modes to generate interrupt to
Cortex
®
-M0, the normal mode and test mode.
The MCU_IRQ collects all interrupts from each peripheral and synchronizes them and
interrupts the Cortex
®
-M0.
When the MCU_IRQ[n] is 0: Set MCU_IRQ[n] 1 will generate an interrupt to Cortex
®
-M0
NVIC[n].
When the MCU_IRQ[n] is 1 (mean an interrupt is assert), setting 1 to the MCU_IRQ[n] 1
will clear the interrupt and setting MCU_IRQ[n] 0: has no effect
