MCU IRQ Source Register
The MCU_IRQ collects all the interrupts from the peripherals and generates the
synchronous interrupt to Cortex-M0 core. 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 then
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), set 1 to the MCU_bit[n] will
clear the interrupt and set MCU_IRQ[n] “0” : no any effect
