217Chapter 6 DMA Functions (DMA Controller)User’s Manual U16580EE3V1UD006.5 DMA Interrupt FunctionThe peripheral I/O interrupts of the A/D converters and the serial interfaces, which serve as DMAtrigger factors, are shared with the DMA transfer completion interrupt of the corresponding channel n(INTDMAn) (n = 0, 1, 4 to 7). When a DMA channel is enabled the specified peripheral I/O interrupt isno longer applied to the interrupt controller. Instead of it the corresponding DMA transfer completioninterrupt is applied to the appropriate interrupt handler address.In opposite to the other interrupts serving as DMA trigger factors, the TMR0 interrupts INTTR0OD andINTTR0CD, and the TMR1 interrupts INTTR1OD and INTTR1CD respectively, are not shared with DMAtransfer completion interrupt of channel 2 (INTDMA2) and channel 3 (INTDMA3) respectively. TheseDMA completion interrupts have dedicated entries in the interrupt source list (refer toTable 7-1: ”Interrupt/Exception Source List” on page 219).Table 6-4 shows the relations between DMA trigger factors and DMA completion interrupts.Notes: 1. Not available on μPD70F3447.2. An interrupt request is not generated for a signal, which serves as DMA trigger factor.Instead of this the defined DMA completion interrupt request is executed on the same inter-rupt entry address of the DMA trigger factor.Table 6-4: Relations Between DMA Trigger Factors and DMA Completion InterruptsDMA channel DMA trigger factor DMA completion interrupt RemarkName Entry HandlerAddress0 INTAD0 INTDMA0 INTAD0 00000670H Note 21 INTAD1 INTDMA1 INTAD1 00000680H Note 22 INTTR0CD orINTR0ODINTDMA2 INTDMA2 000006F0H3 INTTR1CD orINTR1ODINTDMA3 INTDMA3 00000700H4, 5 INTC30 INTDMA4,INTDMA5INTC30 000005E0H Note 2INTC31Note 1 INTC31Note 1 00000600H Note 2INTCB0R INTCB0R 00000580H Note 2INTCB1RNote 1 INTCB1RNote 1 000005B0H Note 2INTUC0R INTUC0R 00000620H Note 2INTUC1R INTUC1R 00000650H Note 26, 7 INTC30 INTDMA6,INTDMA7INTC30 000005E0H Note 2INTC31Note 1 INTC31Note 1 00000600H Note 2INTCB0T INTCB0T 00000570H Note 2INTCB1TNote 1 INTCIB1TNote 1 000005A0H Note 2INTUC0T INTUC0T 00000630H Note 2INTUC1T INTUC1T 00000660H Note 2
