14.2.1 DMAi Source Pointer (SARi) (i = 0 to 3)
DMAi Source Pointer (i = 0 to 3)
(b23) (b16) (b15)
b7 b0 b7
If the DSD bit in the DMiCON register is 0 (fixed), write to SARi register when the DMAE bit in the
DMiCON register is 0 (DMA disabled).
If the DSD bit is 1 (forward direction), this register can be written to at any time.
If the DSD bit is 1 and the DMAE bit is 1 (DMA enabled), the DMAi forward address pointer can be read
from this register. Otherwise, the value written to it can be read.
The forward address pointer increments when a DMA request is accepted.
14.2.2 DMAi Destination Pointer (DARi) (i = 0 to 3)
DMAi Destination Pointer (i = 0 to 3)
(b23) (b16) (b15)
b7 b0 b7
If the DAD bit in the DMiCON register is 0 (fixed), write to the DARi register when the DMAE bit in the
DMiCON register is 0 (DMA disabled).
If the DAD bit is 1 (forward direction), this register can be written to at any time.
If the DAD bit is 1 and the DMAE bit is 1 (DMA enabled), the DMAi forward address pointer can be read
from this register. Otherwise, the value written to it can be read.
The forward address pointer increments when a DMA request is accepted.
