15.4 Operation of DMA Controller
15.4.1 Operation procedure
578
<1> The DMA controller is enabled to operate when DENn = 1. Before writing the other registers, be sure to set
<2> Set an SFR address, a RAM address, the number of times of transfer, and a transfer mode of DMA transfer
<3> The DMA controller waits for a DMA trigger when DSTn = 1. Use 81H to write with an 8-bit manipulation
<4> When a software trigger (STGn) or a start source trigger specified by IFCn3 to IFCn0 is input, a DMA transfer
<5> Transfer is completed when the number of times of transfer set by the DBCn register reaches 0, and transfer
<6> Stop the operation of the DMA controller by clearing DENn to 0 when the DMA controller is not used.
DENn to 1. Use 80H to write with an 8-bit manipulation instruction.
