The DACK output when a transfer occurs from an external device with DACK to a memory-
mapped external device is the write waveform. The DACK output when a transfer occurs from
a memory-mapped external device to an external device with DACK is the read waveform.
The setting of the acknowledge mode (AM) bits in the channel control registers (CHCR0,
CHCR1) have no effect.
