(set HACACR = H'03E0 0000: 20-bit DMATX,
Set read address H'26(Power-down Ctrl/Stat)
Start DMA transfer (Receiver/Transmitter)
HAC cold reset (HACCR = H'0000 0A00)
slot 1 and slot 2 are atomic control)
Set read volume and sampling rate
(1) HACACR = H'0000 0000
(2) Set HACCSAR and HACCSDR
(3) HACACR = H'01E0 0000
ADC, DAC, Analog, REF = ready?
