5.6.1.5

EOnCE Trace Buffer Interrupt Priority Level

(TRBUF IPL)— Bits 5–4

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

5.6.1.6

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

5.6.1.7

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
