Preliminary

5.6.3.5

Low Voltage Detector Interrupt Priority Level (LVI IPL)—Bits 7–6

This field is used to set the interrupt priority level for IRQs. 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

5.6.3.6

Reserved—Bits 5–4

This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.

5.6.3.7

External IRQ B Interrupt Priority Level (IRQB 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.

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

5.6.3.8

External IRQ A Interrupt Priority Level (IRQA IPL)—Bits 1–0

This field is used to set the interrupt priority level for IRQs. 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
