2.3.2.1
IRQ0~31 Interrupt Set-Enable Register (NVIC_ISER)
Address: 0xE000 E100 (Refer to Cortex-M0 Spec.)
The ISER enables interrupts, and shows the interrupts that are enabled.

2.3.2.2
IRQ0~31 Interrupt Clear-Enable Register (NVIC_ICER)

2.3.2.3
IRQ0~31 Interrupt Set-Pending Register (NVIC_ISPR)
Address: 0xE000 E200 (Refer to Cortex-M0 Spec.)
The ISPR forces interrupts into the pending state, and shows the interrupts that are pending.
Note: Writing 1 to the ISPR bit corresponding to
an interrupt that is pending has no effect
a disabled interrupt sets the state of that interrupt to pending.

2.3.2.4
IRQ0~31 Interrupt Clear-Pending Register (NVIC_ICPR)
Address: 0xE000 E280 (Refer to Cortex-M0 Spec.)
The ICPR removes the pending state from interrupts, and shows the interrupts that are pending.
Note: Writing 1 to an ICPR bit does not affect the active state of the corresponding interrupt.
