REGISTER DESCRIPTION

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

6.1

Mode Control 1 - Address 01h

6.1.1

Auto-Mute (Bit 7)

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. (However, Auto-Mute detection and muting can be-

come dependent on either channel if the Mute A = B function is enabled.) The common mode on the

output will be retained and the Mute Control pin for that channel will go active during the mute period.

The muting function is effected, similar to volume control changes, by the Soft and Zero Cross bits in

the Volume and Mixing Control register.

6.1.2

Digital Interface Formats (Bits 6:4)

Function:

PCM Mode - 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 Table 8 and Figures 4-6.
