42.1.8.8 Interrupt Priority Register 2
42.1.8.9 Interrupt Priority Register 3
Table 893. Interrupt Priority Register 1 (IPR1 - address 0xE000 E404) bit
The IPR2 register controls the priority of the third group of 4 peripheral interrupts. Each
interrupt can have one of 32 priorities, where 0 is the highest priority.
Table 894. Interrupt Priority Register 2 (IPR2 - address 0xE000 E408) bit
The IPR3 register controls the priority of the fourth group of 4 peripheral interrupts. Each
interrupt can have one of 32 priorities, where 0 is the highest priority.
