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 the specification by this bit.
This bit is valid only in CHCR_0 to CHCR_3. This bit is
reserved in CHCR_4 to CHCR_7; it is always read as
0 and the write value should always be 0.
0: DACK output in read cycle (dual address mode)
1: DACK output in write cycle (dual address mode)
Acknowledge Level
Specifies the DACK (acknowledge) signal output is
high active or low active.
This bit is valid only in CHCR_0 to CHCR_3. This bit is
reserved in CHCR_4 to CHCR_7; it is always read as
0 and the write value should always be 0.
