Preliminary
5.6.6.3
SCI1 Receiver Full Interrupt Priority Level (SCI1_RCV 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.
They 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
5.6.6.4
SCI1 Receiver Error Interrupt Priority Level (SCI1_RERR 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.
They 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
5.6.6.5
Reserved—Bits 7–6
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.6.6
SCI1 Transmitter Idle Interrupt Priority Level (SCI1_TIDL IPL)—
Bits 5–4
This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.
They 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
5.6.6.7
SCI1 Transmitter Empty Interrupt Priority Level (SCI1_XMIT 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.
They 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
