14.2.4 DMA Channel n Transfer Source Address Register (DCnSA: n = 0, 1)
DCnSA is a special function register (SFR) used to set the transfer source address of channel n.
Specify an existing SFR address or RAM address. If a non-existing address is set, operation is not guaranteed.
In the increment/decrement address mode, an address is incremented or decremented evey transfer. The address is
incremented or decremented once (±1) in the 8-bit data transfer and is incremented or decremented twice (±2) in the
16-bit data transfer. The lowest bit is ignored (d0=0) and even-numbered addresses become the targets in the 16-bit data
transfer.
Address:
0xF704(DC0SAL/DC0SA), 0xF705(DC0SAH),
0xF70C(DC1SAL/DC1SA), 0xF70D(DC1SAH)
Access:

Access size: 8/16bit

[Note]
•
Set the DCnSA register when the transfer is disabled (DCnEN bit = 0). The DCnTN is not writable if the
transfer is enabled (DCnEN bit = 1).
•
If the transfer is stopped (DCnEN bit = 0) before finishing the specified transfer count, the value of the
DCnSA is not guaranteed. Reconfigure the DCnSA when restarting the transfer.
