5.5.1.6 EOnCE Breakpoint Unit Interrupt Priority Level

(BKPT_U IPL)— Bits 3–2

This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 1 through 3.

It is disabled by default.

• 00 = IRQ disabled (default)

• 01 = IRQ is priority level 1

• 10 = IRQ is priority level 2

• 11 = IRQ is priority level 3

5.5.1.7 EOnCE Step Counter Interrupt Priority Level

(STPCNT IPL)— Bits 1–0

This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 1 through 3.

It is disabled by default.

• 00 = IRQ disabled (default)

• 01 = IRQ is priority level 1

• 10 = IRQ is priority level 2

• 11 = IRQ is priority level 3

5.5.2 Interrupt Priority Register 1 (IPR1)

Figure 5-4 Interrupt Priority Register 1 (IPR1)

5.5.2.1 GPIOB Interrupt Priority Level (GPIOB IPL)—Bits 15–14

This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.

It is 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

5.5.2.2 GPIOC Interrupt Priority Level (GPIOC IPL)—Bits 13–12

This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.

It is 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
