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.

Common Area

If A14 and A15 are both true (physical addresses 0xC000 - 0xFFFF), mux the bank address into the top 3 or 4 ROM address bits. Note: A14-A16 for use with 1Mbit ROM 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.
