Preliminary

5.6.3.3 Flash Memory Error Interrupt Priority Level

(FMERR IPL)—Bits 11–10

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

5.6.3.4 PLL Loss of Lock Interrupt Priority Level (LOCK IPL)—Bits 9–8

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

5.6.3.5 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
