Description
Data Transfer Factor 1 and 0
Select a DMAC activation source. When the on-chip
peripheral module setting is selected, the interrupt
source should be selected by DMRSR. When the
external request setting is selected, the sampling
method should be selected by the DREQS bit.
00: Auto request (cycle stealing)
01: Auto request (burst access)
10: On-chip module interrupt
11: External request
Data Transfer Acknowledge
This bit is valid in DMA transfer by the on-chip module
interrupt source. This bit enables or disables to clear the
source flag selected by DMRSR.
0: To clear the source in DMA transfer is disabled.
1: To clear the source in DMA transfer is enabled.
Reserved
These bits are always read as 0 and cannot be
modified.
Since the on-chip module interrupt source is not
cleared in DMA transfer, it should be cleared by the
CPU or DTC transfer.
Since the on-chip module interrupt source is cleared
in DMA transfer, it does not require an interrupt by
the CPU or DTC transfer.
