6.1.1 MCLK DIVIDE-BY-2 (MCLKDIV) BIT 1
Default = 0
0 - Disabled
1 - Enabled
Function:
The MCLKDIV bit enables a circuit which divides the externally applied MCLK signal by 2.

6.2.1 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 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 vol-
ume control changes, by the Soft and Zero Cross bits in the Transition and Mixing Control (address
02h) register.
