8.7.7.3 Timer Channel 0 Input Edge Interrupt Priority Level

(TINP0 IPL)—Bits 11–10

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

8.7.7.4 Timer Channel 0 Overflow Interrupt Priority Level

(TOVF0 IPL)—Bits 9–8

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

8.7.7.5 Timer Channel 0 Compare Interrupt Priority Level

(TCMP0 IPL)—Bits 7–6

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
