• 10 = IRQ is priority level 1
• 11 = IRQ is priority level 2
5.6.4.6 FlexCAN Error Interrupt Priority Level (FCERR 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
5.6.4.7 FlexCAN Bus Off Interrupt Priority Level (FCBOFF 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
5.6.4.8 Reserved—Bits 1–0
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.5 Interrupt Priority Register 4 (IPR4)
Figure 5-7 Interrupt Priority Register 4 (IPR4)
5.6.5.1 SPI 0 Receiver Full Interrupt Priority Level (SPI0_RCV 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.
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
