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 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
