5.2.1 AUTO-MUTE (AMUTE) BIT 7
Default = 1
0 - Disabled
1 - Enabled
Function:
The Digital-to-Analog converter output will mute following the reception of 8192 consecutive audio
samples of static 0 or -1. A single sample of non-zero data will release the mute. Detection and mut-
ing is done independently for each channel. The quiescent voltage on the output will be retained and
the Mute Control pin will go active during the mute period. The muting function is affected, similiar to
volume control changes, by the Soft and Zero Cross bits in the Transition and Mixing Control (address
02h) register.
5.2.2 DIGITAL INTERFACE FORMAT (DIF) BIT 4-6
Default = 000 - Format 0 (I2S, up to 24-bit data)
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 2-4.
5.2.3 DE-EMPHASIS CONTROL ( DEM[1:0] ) BIT 2-3
Default = 00
00 - Disabled
01 - 44.1 kHz
10 - 48 kHz
11 - 32 kHz
Function:
Implementation of the standard 15
s/50s digital de-emphasis filter response, Figure 5, requires re-
configuration of the digital filter to maintain the proper filter response for 32, 44.1 or 48 kHz sample
rates.
NOTE: De-emphasis is only available in Single-Speed Mode.
