4.10.1 Digital Interface Formats (DIF)
Default = 00
00 - I²S
01 - Right Justified, 16 bit
10 - Left Justified
11 - Right Justified, 24 bit
Function:
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 16 through 19.
4.10.2 Channel A Volume = Channel B Volume (A=B)
Default = 0
0 - Disabled
1 - Enabled
Function:
The HP_A and HP_B volume levels are independently controlled by the A and the B Channel Volume
Control Bytes when this function is disabled. The volume on both HP_A and HP_B are determined by the
A Channel Volume Control Byte and the B Channel Byte is ignored when this function is enabled.
4.10.3 Volume Control Bypass (VCBYP)
Default = 0
0 - Disabled
1 - Enabled
Function:
The digital volume control section is bypassed when this function is enabled. This disables the digital vol-
ume control, muting, bass boost, treble boost, limiting, and ATAPI functions.
4.10.4 Control Port Enable (CP_EN)
Default = 0
0 - Disabled
1 - Enabled
Function:
This bit defaults to 0, allowing the device to power-up in Stand-Alone mode. The Control Port Mode can
be accessed by setting this bit to 1. This will allow the operation of the device to be controlled by the reg-
isters and the pin definitions will conform to Control Port Mode. Refer to Section 6.5.2.
