Bit 17—Acknowledge Mode (AM): AM specifies whether DACK is output in data read cycle or
in data write cycle in dual address mode.
In single address mode, DACK is always output regardless of this bit specification.
This bit is only valid in CHCR0. This bit in CHCR1, CHCR2 and CHCR3 is always read as 0 and
should only be written with 0.
Bit 17: AM

Bit 16—Acknowledge Level (AL): AL specifies the DACK (acknowledge) signal output is high
active or low active.
This bit is only valid in CHCR0. This bit in CHCR1, CHCR2 and CHCR3 is always read as 0 and
should only be written with 0.
Bit 16: AL

Bits 15 and 14—Destination Address Mode 1, 0 (DM1 and DM0): DM1 and DM0 select
whether the DMA destination address is incremented, decremented, or fixed.
Bit 15: DM1
0

Description
DACK output in read cycle
DACK output in write cycle
Description
Low-active output of DACK
High-active output of DACK
Fixed destination address*
Destination address is incremented (+1 in 8-bit transfer, +2 in
16-bit transfer, +4 in 32-bit transfer, +16 in 16-byte transfer)
Destination address is decremented (–1 in 8-bit transfer, –2 in
16-bit transfer, –4 in 32-bit transfer; illegal setting in 16-byte
transfer)
Reserved (illegal setting)
