Name: DMAC_SGRx
Addresses:0x00800048 [0], 0x008000A0 [1]
Access: Read-write
Reset: 0x0
The address offset for each channel is: 0x48+[x * 0x58]
For example, SGR0: 0x048, SGR1: 0x0a0, etc.
The DMAC_CTLx.SINC field controls whether the address increments or decrements. When the DMAC_CTLx.SINC field
indicates a fixed-address control, then the address remains constant throughout the transfer and the DMAC_SGRx register
is ignored.
• SGI: Source Gather Interval
Source gather count field specifies the number of contiguous source transfers of DMAC_CTLx.SRC_TR_WIDTH between
successive gather intervals. This is defined as a gather boundary.
• SGC: Source Gather Count
Source gather interval field (DMAC_SGRx.SGI) – specifies the source address increment/decrement in multiples of
DMAC_CTLx.SRC_TR_WIDTH on a gather boundary when gather mode is enabled for the source transfer.
