Resource Select 3 to 0
Specify which transfer requests will be sent to the
DMAC. The changing of transfer request source should
be done in the state that the DMA enable bit (DE) is
cleared to 0.
0000: External request, dual address mode
0100: Auto request
1000: Selected by DMA extended resource selector (for
Other than above: Setting prohibited
Note: External request specification is valid only in
DREQ Level and DREQ Edge Select
Specify the detecting method of the DREQ pin input
and the detecting level.
These bits are valid only in CHCR0 to CHCR3.
In channels 0 to 3, also, if the transfer request source is
specified as a peripheral module or if an auto-request is
specified, these bits are invalid.
00: DREQ detected in low level (DREQ)
01: DREQ detected at falling edge
10: DREQ detected in high level
11: DREQ detected at rising edge
Transfer Bus Mode
Specifies the bus mode when DMA transfers data.
0: Cycle steal mode
1: Burst mode
Select the cycle steal mode when the peripheral module
requests.
DMA Transfer Size Specify
