84 / 164 page  56F8355 Technical Data, Rev. 12 84 Freescale Semiconductor Preliminary 5.6.5 Interrupt Priority Register 4 (IPR4) Figure 5-7 Interrupt Priority Register 4 (IPR4) 5.6.5.1 SPI0 Receiver Full Interrupt Priority Level (SPI0_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. 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 5.6.5.2 SPI1 Transmit Empty Interrupt Priority Level (SPI1_XMIT 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. 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 5.6.5.3 SPI1 Receiver Full Interrupt Priority Level (SPI1_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 5.6.5.4 Reserved—Bits 9–6 This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
