REGISTER DESCRIPTIONS

Note: All registers are read/write in I²C mode and write only in SPI, unless otherwise stated.

6.1

MODE CONTROL 1 (ADDRESS 01H)

6.1.1

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-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 become 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.

6.1.2

DIGITAL INTERFACE FORMAT (DIF)

BIT 4-6

Default

= 000

- Format 0 (Left Justified, 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 15-17.
