Freescale Semiconductor 73
Preliminary
5.6.9.3 Reserved—Bits 11–10
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.9.4 SCI0 Transmitter Idle Interrupt Priority Level (SCI0 TIDL 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
5.6.9.5 SCI0 Transmitter Empty Interrupt Priority Level (SCI0 XMIT 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.
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
5.6.9.6 Timer A, Channel 3 Interrupt Priority Level (TMRA 3 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
5.6.9.7 Timer A, Channel 2 Interrupt Priority Level (TMRA 2 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.
