5.5.2.8
PLL Loss of Reference or Change in Lock Status Interrupt Priority Level
(PLL 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

Interrupt Priority Register 2 (IPR2)
Figure 5-5 Interrupt Priority Register 2 (IPR2)
5.5.3.1
SCI Receiver Full Interrupt Priority Level (SCI_RCV IPL)—
Bits 15–14
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
5.5.3.2
SCI Receiver Error Interrupt Priority Level (SCI_RERR IPL)—
Bits 13–12
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
5.5.3.3
Reserved—Bits 11–10
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
