DMA0_SAR_U = F0h, DMA1_SAR_L = F7h, DMA1_SAR_H = F8h, DMA1_SAR_U = F9h
These two groups of registers hold the 24-bit addresses of the source memory location for
DMA Channel 0 and Channel 1. Depending upon settings within the DMA Control regis-
ters’ SARx_CTL fields, the 24-bit address values can automatically be incremented, dec-
remented, or unchanged following the transfer of each byte of data. See
