Preliminary
5.6.2.6
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.
FM Command Complete Priority Level (FM_CC IPL)—Bits 5–4
00 = IRQ disabled (default)
01 = IRQ is priority level 0
10 = IRQ is priority level 1
11 = IRQ is priority level 2
5.6.2.7
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.
FM Error Interrupt Priority Level (FM_ERR IPL)—Bits 3–2
00 = IRQ disabled (default)
01 = IRQ is priority level 0
10 = IRQ is priority level 1
11 = IRQ is priority level 2
5.6.2.8
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
