20.10 DMA Abort Factors
memory/on-chip peripheral I/O.
20.11 End of DMA Transfer
bit is cleared to 0 and TCn bit is set to 1, a DMA transfer end interrupt request signal (INTDMAn) is generated for the
interrupt controller (INTC) (n = 0 to 3).
DMA transfer by using the DMA transfer end interrupt or polling the TCn bit.
20.12 Operation Timing
DMA transfer is aborted if a bus hold occurs.
The same applies if transfer is executed between the internal memory/on-chip peripheral I/O and internal
When the bus hold is cleared, DMA transfer is resumed.
When DMA transfer has been completed the number of times set to the DBCn register and when the DCHCn.Enn
The V850ES/JG3-L does not output a terminal count signal to an external device. Therefore, confirm completion of
The operation timing of DMA is as follows.
Four examples are shown:
• Multiple channels request DMA transfer simultaneously (see Figure 20-4).
• A new DMA transfer with a higher priority is requested during a DMA transfer (see Figure 20-5).
• A new DMA transfer request for the same channel is ignored (one channel) (see Figure 20-6).
• A new DMA transfer request for the same channel is ignored (multiple channels) (see Figure 20-7).
