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. It is invalid in DDT mode.
Bit 16: AL

1
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.
Bit 15: DM1
0
1
Bits 13 and 12—Source Address Mode 1 and 0 (SM1, SM0): These bits specify
incrementing/decrementing of the DMA transfer source address. The specification of these bits is
ignored when data is transferred from an external device to external memory in single address
mode.
