Information

3.2.2.3 Interrupt channel assignments
The interrupt source assignments are defined in the following table.
• Vector number — the value stored on the stack when an interrupt is serviced.
• IRQ number — non-core interrupt source count, which is the vector number minus
16.
The IRQ number is used within ARM's NVIC documentation.
