Table 6.3 shows the correspondence between the interrupt request sources and the bits in IPR01, IPR02, and IPR06 to IPR16. 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 0000000000000000 R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W Bit: Initial value: R/W: Table 6.3 Interrupt Request Sources and IPR01, IPR02, and IPR06 to IPR16 Register Name Bits 15 to 12 Bits 11 to 8 Bits 7 to 4 Bits 3 to 0 Interrupt priority register 01 IRQ0 IRQ1 IRQ2 IRQ3 Interrupt priority register 02 IRQ4 IRQ5 IRQ6 IRQ7 Interrupt priority register 06 DMAC0 DMAC1 DMAC2 DMAC3 Interrupt priority register 07 DMAC4 DMAC5 DMAC6 DMAC7 Interrupt priority register 08 USB Reserved CMT0 CMT1 Interrupt priority register 09 BSC WDT HIF0 HIF1 Interrupt priority register 10 ADM1I C[0]I C[1]I Reserved Interrupt priority register 11 Reserved Reserved FECI Reserved Interrupt priority register 12 ETC IIC3 Reserved STIF0 Interrupt priority register 13 STIF1 SCIF0 SCIF1 SCIF2 Interrupt priority register 14 Reserved Reserved Reserved SSI0 |
