When the DAR reload function is enabled, the RDAR value is written to the destination address register (SAR) at the end of the current DMA transfer. In this case, a new value for the next DMA transfer can be preset in RDAR during the current DMA transfer. When the DAR reload function is disabled, RDAR is ignored. To transfer data in word (2-byte), longword (4-byte), or 16-byte unit, specify the address with 2- byte, 4-byte, or16-byte address boundary respectively. 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 0000000000000000 R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W 0000000000000000 R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W Bit: Initial value: R/W: Bit: Initial value: R/W: |
