Destination address mode.

0 Increment (INCR) mode. Destination addressing within an array increments. Destination is not a FIFO.

1 -Constant addressing (CONST) mode. Destination addressing within an array wraps around upon reaching FIFO width. Note: The constant addressing (CONST) mode has limited applicability. The EDMA3 should be configured for the constant addressing mode (SAM/DAM = 1) only if the transfer source or destination (on-chip memory, off-chip memory controllers, slave peripherals) support the constant addressing mode. On the C674x/OMAP-L1x processors, no peripherals, memory, or memory controller support constant addressing mode. If the constant addressing mode is not supported, the similar logical transfer can be achieved using the increment (INCR) mode (SAM/DAM = 0) by appropriately programming the count and indices values
