5.6.2 Interrupt Priority Register 1 (IPR1)
Figure 5-4 Interrupt Priority Register 1 (IPR1)
5.6.2.1 GPIOD Interrupt Priority Level (GPIOD IPL)—Bits 15–14
This field is used to set the interrupt priority level for the GPIOD IRQ. 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
5.6.2.2 MSCAN Wake Up Interrupt Priority Level
(MSCAN_WKUP IPL)—Bits 13–12
This field is used to set the interrupt priority level for the MSCAN Wake Up IRQ. 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
5.6.2.3 MSCAN Transmit Interrupt Priority Level (MSCAN_TX IPL)—Bits 11–10
This field is used to set the interrupt priority level for the MSCAN Transmit IRQ. 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
5.6.2.4 MSCAN Receive Interrupt Priority Level (MSCAN_RX IPL)—Bits 9–8
This field is used to set the interrupt priority level for MSCAN Receive IRQ. 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
