Bit 17—Acknowledge Mode Bit (AM): Specifies whether DACK is output in the data read cycle
or in the data write cycle in dual address mode.
This bit is only valid in CHCR0 and CHCR1. Writing to this bit is invalid in CHCR2 and
CHCR3; 0 is read if this bit is read.

Bit 16—Acknowledge Level (AL): Specifies whether DACK (acknowledge) signal output is
active-high or active-low.
This bit is only valid in CHCR0 and CHCR1. Writing to this bit is invalid in CHCR2 and
CHCR3; 0 is read if this bit is read.
