Description
Destination Address Mode
Specify whether the DMA destination address is
incremented, decremented, or left fixed. (In single address
mode, the DM1 and DM0 bits are ignored when data is
transferred to an external device with the DACK.)
00: Fixed destination address (setting prohibited in 16-byte
01: Destination address is incremented (+1 in byte transfer,
10: Destination address is decremented (–1 in byte transfer,
11: Reserved (setting prohibited)
Source Address Mode
Specify whether the DMA source address is incremented,
decremented, or left fixed. (In single address mode, the
SM1 and SM0 bits are ignored when data is transferred
from an external device with the DACK.)
00: Fixed source address (setting prohibited in 16-byte
01: Source address is incremented (+1 in byte transfer, +2
10: Source address is decremented (–1 in byte transfer, –2
