Preliminary
5.6.1
Interrupt Priority Register 0 (IPR0)
Figure 5-3 Interrupt Priority Register 0 (IPR0)
5.6.1.1
Reserved—Bits 15–14
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.1.2
EOnCE Breakpoint Unit 0 Interrupt Priority Level (BKPT_U0 IPL)—
Bits13–12
This field is used to set the interrupt priority levels 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
5.6.1.3
EOnCE Step Counter Interrupt Priority Level (STPCNT IPL)—Bits 11–10
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
5.6.1.4
Reserved—Bits 9–0
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
