24.4.9 Destination Scatter Register for Channel x
Name: DMAC_DSRx
Address: 0x00800050 [0], 0x008000A8 [1]
Access: Read/Write
The address offset for each channel is: 0x50+[x * 0x58]
For example, DSR0: 0x050, DSR1: 0x0a8, etc.
The DMAC_CTLx.DINC field controls whether the address increments or decrements. When the DMAC_CTLx.DINC field
indicates a fixed address control then the address remains constant throughout the transfer and the DMAC_DSRx is
ignored.
• DSI: Destination Scatter Interval
Destination scatter interval field (DMAC_DSRx.DSI) – specifies the destination address increment/decrement in multiples
of DMAC_CTLx.DST_TR_WIDTH on a scatter boundary when scatter mode is enabled for the destination transfer.
• DSC: Destination Scatter Count
Destination scatter count field (DMAC_DSRx.DSC) – specifies the number of contiguous destination transfers of
DMAC_CTLx.DST_TR_WIDTH between successive scatter boundaries.
