8.7.6.8 SPI Transmitter Empty Interrupt Priority Level

(SPI_XMIT IPL)—Bits 1–0

This bit field is used to set the interrupt priority levels for certain peripheral IRQs. These

IRQs are limited to priorities zero through two and 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

8.7.7 Interrupt Priority Register 6 (IPR6)

Figure 8-9. Interrupt Priority Register 6 (IPR6)

See Programmer’s Sheet on Appendix page B - 31

8.7.7.1 Timer Channel 1 Overflow Interrupt Priority Level

(TOVF1 IPL)—Bits 15–14

This bit field is used to set the interrupt priority levels for certain peripheral IRQs. These

IRQs are limited to priorities zero through two and 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

8.7.7.2 Timer Channel 1 Compare Interrupt Priority Level

(TCMP1 IPL)—Bits 13–12

This bit field is used to set the interrupt priority levels for certain peripheral IRQs. These

IRQs are limited to priorities zero through two and 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
