It is read as 0 and cannot be modified by writing. 5.6.5.5 GPIOA Interrupt Priority Level (GPIOA IPL)—Bits 5–4 This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2. They are disabled by default. • 00 = IRQ disabled (default) • 01 = IRQ is priority level 0 • 10 = IRQ is priority level 1 • 11 = IRQ is priority level 2 5.6.5.6 GPIOB Interrupt Priority Level (GPIOB IPL)—Bits 3–2 This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2. They are disabled by default. • 00 = IRQ disabled (default) • 01 = IRQ is priority level 0 • 10 = IRQ is priority level 1 • 11 = IRQ is priority level 2 5.6.5.7 GPIOC Interrupt Priority Level (GPIOC IPL)—Bits 1–0 This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2. They are disabled by default. • 00 = IRQ disabled (default) • 01 = IRQ is priority level 0 • 10 = IRQ is priority level 1 • 11 = IRQ is priority level 2 5.6.6 Interrupt Priority Register 5 (IPR5) Figure 5-8 Interrupt Priority Register 5 (IPR5) 5.6.6.1 Quadrature Decoder 1 INDEX Pulse Interrupt Priority Level (DEC1_XIRQ IPL)—Bits 15–14 This field is used to set the interrupt priority level for IRQs.
