8.7.7.6 Time of Day 1 Second Interval Interrupt Priority Level

(TOD1 IPL)—Bits 5–4

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

8.7.7.7 Time of Day Alarm Interrupt Priority Level

(TOD_ALRM IPL)—Bits 3–2

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

8.7.7.8 Host I/F Command Interrupt Priority Level

(HOST_CMD 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
