—
1. Indicates the NVIC's interrupt source number.
2. Indicates the NVIC's ISER, ICER, ISPR, ICPR, and IABR register number used for this IRQ. The equation to calculate this
value is: IRQ div 32
3. Indicates the NVIC's IPR register number used for this IRQ. The equation to calculate this value is: IRQ div 4
4. This interrupt can only be pended or cleared via the NVIC registers.
3.2.2.3.1 Determining the bitfield and register location for configuring a
particular interrupt
Suppose you need to configure the low-power timer (LPTMR) interrupt. The following
table is an excerpt of the LPTMR row from Interrupt channel assignments.
