6. REGISTER DESCRIPTION
** All register access is R/W unless specified otherwise**
6.1
Chip ID - Register 01h
Function:
This register is Read-Only. Bits 7 through 3 are the part number ID which is 11111b and the remaining Bits
(2 through 0) are for the chip revision (Rev. A = 000, Rev. B = 001, ...)
6.2
Mode Control 1 - Register 02h
6.2.1
Digital Interface Format (DIF2:0) Bits 6-4
Function:
These bits select the interface format for the serial audio input.
The required relationship between the Left/Right clock, serial clock and serial data is defined by the Digital
Interface Format and the options are detailed in Figures 5 through 7.
6.2.2
De-Emphasis Control (DEM1:0) Bits 3-2.
Default = 0
00 - No De-emphasis
01 - 44.1 kHz De-emphasis
10 - 48 kHz De-emphasis
11 - 32 kHz De-emphasis
Function:
Selects the appropriate digital filter to maintain the stan-
dard 15
s/50 s digital de-emphasis filter response at
32, 44.1 or 48 kHz sample rates. (See Figure 11.)
Note:
De-emphasis is only available in Single-Speed Mode
