(1) External Request 2-Channel Mode
Examples of transfer of data in external memory to an external device with DACK using DMAC
channel 1 in external request 2-channel mode are considered here.
Table 11.11 (1) shows the transfer conditions and the corresponding register settings.
Table 11.11 (1) Conditions for Transfer between External Memory and External Device
Note: * When DREQ1 is specified as a DMA transfer request source in external request 2-channel
mode, only channel 1 accepts the DMA transfer request (DREQ0 is accepted only by
channel 0).
