Bit 16—Acknowledge Level (AL): Specifies the DACK (acknowledge) signal as active-high or
active-low.
In normal DMA mode, this bit is valid only in CHCR0 and CHCR1. In DDT mode, this bit is
invalid.

Bits 15 and 14—Destination Address Mode 1 and 0 (DM1, DM0): These bits specify
incrementing/decrementing of the DMA transfer destination address. The specification of these
bits is ignored when data is transferred from external memory to an external device in single
address mode. For channel 0, in DDT mode these bits are set to DM1 = 0 and DM0 = 1 with the
DTR format.
