AKM 96/24 Series II Audio System operation notes:
Tweeked I2C (need to simulate SPI) for controlling the 74HC595 register.
A/D operates in Slave Mode.
~PDN, 0=Power Down
DFS, 0 for 256fs Normal, 1 for 128fs Double Speed,
D/A operation.
DFS, Double Speed =0 for 256fs, Double Speed =1 for 128fs, see below...
DEM1, DEM0, DFS MODE
0 0 0 44.1kHz
1 0 0 48.0kHz
1 1 0 32.0kHz
1 0 1 96.0kHz
~PDN, 0=Power Down
!!!!!! NOTE: DUE to the AKMs (A/D and D/A) internal dynamic refresh logic, they
recommend NO prolonged periods of time without external clock input.

If A14 and A15 are both true (physical addresses
0xC000 - 0xFFFF), mux the bank address into the top
3 or 4 ROM address bits.
or A14-A17 for use with 2 Mbit ROM.
Else in the common area of the ROM so use A14
and A15, and force A16 & A17 to zero.
