Interrupt Priority Register 4 (IPR4)
Figure 5-7 Interrupt Priority Register 4 (IPR4)
5.6.5.1
SPI 0 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
SPI 1 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
SPI 1 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.
