REGISTER DESCRIPTIONS

Note: All registers are read/write in Two-Wire mode and write only in SPI, unless otherwise noted.

4.1

Mode Control 1 (address 01h)

4.1.1

AUTO-MUTE (AMUTE)

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-static data will release the mute. Detection and

muting 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, similar

to volume control changes, by the Soft and Zero Cross bits in the Power and Muting Control register.

4.1.2

DIGITAL INTERFACE FORMAT (DIF)

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 17-22.
