Preliminary
5.6.3.5
Low Voltage Detector Interrupt Priority Level (LVI IPL)—Bits 7–6
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
5.6.3.6
Reserved—Bits 5–2
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.3.7
External IRQ A Interrupt Priority Level (IRQA 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.
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
5.6.4
Interrupt Priority Register 3 (IPR3)
Figure 5-6 Interrupt Priority Register 3 (IPR3)
5.6.4.1
Reserved—Bits 15–10
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.4.2
FlexCAN Message Buffer Interrupt Priority Level
(FCMSGBUF IPL)—Bits 9–8
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
