0x0000_01B8 110 94 2 23 Software Software interrupt

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.
