Chapter 6: LPC13xx Interrupt controller
6.6.17 Interrupt Priority Register 6
The IPR6 register controls the priority of four peripheral interrupts. Each interrupt can
have one of 32 priorities, where 0 is the highest priority.
6.6.18 Interrupt Priority Register 7
The IPR7 register controls the priority of four peripheral interrupts. Each interrupt can
have one of 32 priorities, where 0 is the highest priority.
